general description the max5214/max5216 are pin-compatible, 14-bit and 16-bit digital-to-analog converters (dacs). the max5214/ max5216 are single-channel, low-power, buffered volt - age-output dacs. the devices use a precision external reference applied through the high resistance input for rail-to-rail operation and low system power consumption. the max5214/max5216 accept a wide 2.7v to 5.5v sup - ply voltage range. power consumption is extremely low to accommodate most low-power and low-voltage appli - cations. these devices feature a 3-wire spi-/qspi?-/ microwire-/dsp-compatible serial interface to save board space and to reduce the complexity in isolated applications. the max5214/max5216 minimize the digi - tal noise feedthrough from input to output with sclk and din input buffers powered down after completion of each serial input frame. on power-up, the max5214/max5216 reset the dac output to zero, providing additional safety for applications that drive valves or other transducers that need to be off on power-up. the dac output is buffered resulting in a low supply current of 80 a (max) and a low offset error of 0.25mv. a zero level applied to the clr pin asynchronously clears the contents of the input and dac registers and sets the dac output to zero indepen - dent of the serial interface. the max5214/max5216 are available in an ultra-small (3mm x 5mm), 8-pin max? package and are specified over the -40 c to +105 c extended industrial temperature range. applications 2-wire sensors communication systems automatic tuning gain and offset adjustment power ampliier control process control and servo loops portable instrumentation programmable voltage and current sources automatic test equipment beneits and features low power consumption (80a max) 14-/16-bit resolution in a 3mm x 5mm, 8-pin max package relative accuracy ? 0.40 lsb inl (max5214, 14-bit typ, 1 lsb max) ? 1.2 lsb inl (max5216, 16-bit typ, 4 lsb max) guaranteed monotonic over all operating ranges low gain and offset error wide 2.7v to 5.5v supply range rail-to-rail buffered output operation safe power-on reset (por) to zero dac output fast 50mhz, 3-wire, spi/qspi/microwire compatible serial interface schmitt-trigger inputs for direct optocoupler interface asynchronous clr clears dac output to code 0 high reference input resistance for power reduction buffered voltage output directly drives 10k loads ordering information appears at end of data sheet. 19-5651; rev 2; 7/13 qspi is a trademark of motorola, inc. max is a registered trademark of maxim integrated products, inc. functional diagram se ri al-to- parallel co nve rte r input register dac register clr por 14-/16-bit dac buffer cs sc lk din gnd out max5214max5216 v dd ref max5214/max5216 14-/16-bit, low-power, buffered output, rail-to-rail dacs with spi interface evaluation kit available downloaded from: http:///

detailed description the max5214/max5216 are pin-compatible and soft - ware-compatible 14-bit and 16-bit dacs. the max5214/max5216 are single-channel, low-power, high-refer - ence input resistance, and buffered voltage-output dacs. the max5214/max5216 minimize the digital noise feedthrough from their inputs to their outputs by powering down the sclk and din input buffers after completion of each data frame. the data frames are 16-bit for the max5214 and 24-bit for the max5216. on power-up, the max5214/max5216 reset the dac output to zero, providing additional safety for applications that drive valves or other transducers which need to be off on power-up. the max5214/max5216 contain a segmented resistor string-type dac, a serial-in/parallel-out shift reg - ister, a dac register, power-on-reset (por) circuit, clr to asynchronously clear the device independent of the serial interface, and control logic. on the falling edge of the clock (sclk) pulse, the serial input (din) data is shifted into the device, msb first. output ampliier (out) the max5214/max5216 include an internal buffer on the dac output. the internal buffer provides improved load regulation and transition glitch suppression for the dac output. the output buffer slews at 0.5v/ f s and drives up to 10k i in parallel with 100pf. the analog supply voltage (v dd ) determines the maximum output voltage range of the device as v dd powers the output buffer. dac reference (ref)the external reference input features a typical input impedance of 256k i and accepts an input voltage from +2v to v dd . connect an external voltage supply between ref and gnd to apply an external reference.visit www.maximintegrated.com/products/references for a list of available voltage-reference devices. pin description pin coniguration ou t cl r di n 12 8 7 gn d v dd cs sc lk re f m ax top view 3 4 6 5 max5214max5216 + pin name function 1 ref reference voltage input. bypass ref with a 0.1f capacitor to gnd. 2 cs active-low chip-select input 3 sclk serial-clock input 4 din data in 5 clr active-low asynchronous digital-clear input. drive clr low to clear the contents of the input and dac registers and set the dac output to zero. 6 out buffered dac voltage output 7 v dd supply voltage. bypass v dd with a 0.1f capacitor to gnd. 8 gnd ground www.maximintegrated.com maxim integrated 12 max5214/max5216 14-/16-bit, low-power, buffered output, rail-to-rail dacs with spi interface downloaded from: http:///
serial interfacethe max5214/max5216 3-wire serial interface is com - patible with microwire, spi, qspi, and dsp. the interface provides three inputs: sclk, cs , and din. the chip-select input ( cs ) frames the serial data loading at din. following a chip-select input high-to-low transition, the data is shifted synchronously and latched into the input register on each falling edge of the serial-clock input (sclk). each serial word is 16-bit for the max5214 and 24-bit for the max5216. the first 2 bits are the control bits followed by 14 data bits (msb first) for the max5214 and 22 data bits (msb first) for the max5216 as shown in table 1 and table 2 . the serial input register transfers its contents to the input registers after loading 16/24 bits of data and updates the dac output immedi - ately after the data is received on the 16-/24-bit falling edge of the clock. to initiate a new data transfer, drive cs high and keep cs high for a minimum of 20ns before the next write sequence. the sclk can be either high or low between cs write pulses. figure 1 and figure 2 show the timing diagram for the complete 3-wire serial inter - face transmission. the max5216 dac code is unipolar binary with v out = (code/65,535) x v ref . the max5214 dac code is unipolar binary with v out = (code/16,383) x v ref . see table 1 and table 2 . table 1. operating mode truth table (max5214) table 2. operating mode truth table (max5216) 16-bit word function control bits data bits msb lsb d15 d14 d13 d12 d11 d10 d9 d8 d7 d6 d5 d4 d3 d2 d1 d0 0 0 x x x x x x x x x x x x x x no operation 1 0 0 x a1 a0 x x x x x x x x x x power-down(see table 3) 0 1 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0 write through 1 1 reserved, do not use 24-bit word function control bits data bits msb lsb d23 d22 d21 d20 d19 d18 d17 d16 d15 d14 d13 d12 d11 d10 d9 d8 d7 d6 d5? d0 0 0 x x x x x x x x x x x x x x x x x no operation 1 0 0 x a1 a0 x x x x x x x x x x x x x power-down(see table 3) 0 1 b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0 x write through 1 1 reserved, do not use www.maximintegrated.com maxim integrated 13 max5214/max5216 14-/16-bit, low-power, buffered output, rail-to-rail dacs with spi interface downloaded from: http:///
writing to the devices 1) drive cs low, enabling the shift register. 2) clock 16/24 bits of data into din (msb first and lsb last), observing the specified setup and hold times. 3) after clocking in the last data bit, drive cs high. cs must remain high for 20ns before the next transmis - sion is started. figure 1 shows a write operation for the transmission of 16 bits. if cs is driven high at any point prior to receiving 16 bits, the transmission is discarded . figure 2 shows a write operation for the transmission of 24 bits. if cs is driven high at any point prior to receiving 24 bits, the transmission is discarded.clear ( clr ) the max5214/max5216 feature an asynchronous active-low clr logic input that sets the dac output to zero. driving clr low clears the contents of both the input and dac registers and also aborts the on-going spi com - mand. to allow a new spi command, drive clr high. power-down modethe max5214/max5216 feature a software-controlled power-down mode. in power-down, the output discon - nects from the buffer and is grounded with one of the three selectable internal resistors. see table 3 for the selectable internal resistor values in power-down mode. the selected mode takes effect on the 16th sclk falling edge of the max5214 and 24th sclk falling edge of the max5216. the serial interface remains active in power- down mode. in order to abort the power-down mode selection, pull cs high prior to the 16th (max5214) or 24th (max5216) sclk falling edge. the contents of the dac register remain valid while in power-down mode, allowing for the dac to return to previous code by writing 0x8000 for the max5214 or 0x800000 for the max5216 ( table 3 ). a write to the write-through register causes the device to immediately exit power-down mode and transi - tion to the requested code (see table 1 and table 2 ). table 3. power-down modes table 4. max5216 input code vs. output voltage table 5. max5214 input code vs. output voltage a1 a0 description dac operation condition 0 0 dac powers up and returns to its previous code setting. normal operation 0 1 dac powers down; out is high impedance. power-down 1 0 dac powers down; out connects to ground through an internal 100k i resistor. 1 1 dac powers down; out connects to ground through an internal 1k i resistor. dac latch contents analog output (v out ) msb g lsb 1111 1111 1111 11xx v ref x (16,383/16,383) 1000 0000 0000 00xx v ref x (8,192/16,383) = 1/2 v ref 0000 0000 0000 01xx v ref x (1/16,383) 0000 0000 0000 00xx 0v dac latch contents analog output (v out ) msb g lsb 1111 1111 1111 1111 v ref x (65,535/65,535) 1000 0000 0000 0000 v ref x (32,768/65,535) = 1/2 v ref 0000 0000 0000 0001 v ref x (1/65,535) 0000 0000 0000 0000 0v www.maximintegrated.com maxim integrated 14 max5214/max5216 14-/16-bit, low-power, buffered output, rail-to-rail dacs with spi interface downloaded from: http:///
applications information power-on reset (por)when first power is applied to v dd , the input registers are set to zero so the dac output is set to code zero. to optimize dac linearity, wait until the supplies have settled. the max5214/max5216 output voltage range is 0 to v ref . power supplies and bypassing considerationsbypass v dd with high-quality 0.1f ceramic capacitors to a low-impedance ground as close as possible to the device. minimize lead lengths to reduce lead inductance. connect the gnd to the analog ground plane. layout considerations digital and ac transient signals on gnd can create noise at the output. connect gnd to the star ground for the dac system. refer the remote dac loads to this system ground for the best possible performance. use proper grounding techniques, such as a multilayer board with a low-inductance ground plane, or star connect all ground return paths back to the max5214/max5216 gnd. carefully lay out the traces between channels to reduce ac cross-coupling. do not use wire-wrapped boards and sockets. use shielding to improve noise immunity. do not run analog and digital signals parallel to one another, especially clock signals. avoid routing digital lines underneath the max5214/max5216 package. deinitions integral nonlinearity (inl)inl is the deviation of the measured transfer function from a straight line drawn between two codes once offset and gain errors have been nullified. differential nonlinearity (dnl) dnl is the difference between an actual step height and the ideal value of 1 lsb. if the magnitude of the dnl is greater than -1 lsb, the dac guarantees no missing codes and is monotonic. offset erroroffset error indicates how well the actual transfer func - tion matches the ideal transfer function at a single point.typically, the point at which the offset error is specified is at or near the zero-scale point of the transfer function. gain error gain error is the difference between the ideal and the actual full-scale output voltage on the transfer curve, after nullifying the offset error. this error alters the slope of the transfer function and corresponds to the same percentage error in each step. settling time the settling time is the amount of time required from the start of a transition, until the dac output settles to the new output value within the converter?s specified accuracy. digital feedthrough digital feedthrough is the amount of noise that appears on the dac output when the dac digital control lines are toggled. digital-to-analog glitch impulse a major carry transition occurs at the midscale point where the msb changes from low to high and all other bits change from high to low, or where the msb changes from high to low and all other bits change from low to high. the duration of the magnitude of the switching glitch during a major carry transition is referred to as the digital-to-analog glitch impulse. digital-to-analog power-up glitch impulse the digital-to-analog power-up glitch is the duration of the magnitude of the switching glitch that occurs as the device exits power-down mode. www.maximintegrated.com maxim integrated 15 max5214/max5216 14-/16-bit, low-power, buffered output, rail-to-rail dacs with spi interface downloaded from: http:///
