? 2009-2011 microchip technology inc. ds22141b-page 11 mcp6l91/1r/2/4 4.0 application information the mcp6l91/1r/2/4 family of op amps is manufac- tured using microchips state of the art cmos process. it is designed for low cost, low power and general pur- pose applications. the low supply voltage, low quiescent current and wide bandwidth makes the mcp6l91/1r/2/4 ideal for battery-powered applica- tions. 4.1 rail-to-rail inputs 4.1.1 phase reversal the mcp6l91/1r/2/4 op amps are designed to prevent phase inversion when the input pins exceed the supply voltages. figure 2-10 shows an input voltage exceeding both supplies without any phase reversal. 4.1.2 input voltage and current limits in order to prevent damage and/or improper operation of these amplifiers, the circuit they are in must limit the currents (and voltages) at the input pins (see section 1.1 absolute maximum ratings ? ). figure 4-1 shows the recommended approach to protecting these inputs. the internal esd diodes prevent the input pins (v in + and v in C) from going too far below ground, and the resistors r 1 and r 2 limit the possible current drawn out of the input pins. diodes d 1 and d 2 prevent the input pins (v in + and v in C) from going too far above v dd , and dump any currents onto v dd . figure 4-1: protecting the analog inputs. a significant amount of current can flow out of the inputs (through the esd diodes) when the common mode voltage (v cm ) is below ground (v ss ); see figure 2-7 . applications that are high-impedance may need to limit the usable voltage range. 4.1.3 normal operation the input stage of the mcp6l91/1r/2/4 op amps use two differential cmos input stages in parallel. one operates at low common mode input voltage (v cm ), while the other operates at high v cm . with this topology, and at room temperature, the device operates with v cm up to 0.3v above v dd and 0.3v below v ss (typical at 25c). the transition between the two input stages occurs when v cm =v dd C 1.1v. for the best distortion and gain linearity, with noninverting gains, avoid this region of operation. 4.2 rail-to-rail output the output voltage range of the mcp6l91/1r/2/4 op amps is v dd C 20 mv (minimum) and v ss +20mv (maximum) when r l =10k ? is connected to v dd /2 and v dd = 5.0v. refer to figure 2-13 for more informa- tion. 4.3 capacitive loads driving large capacitive loads can cause stability problems for voltage feedback op amps. as the load capacitance increases, the feedback loops phase margin decreases and the closed-loop bandwidth is reduced. this produces gain peaking in the frequency response, with overshoot and ringing in the step response. when driving large capacitive loads with these op amps (e.g., > 100 pf when g = +1), a small series resistor at the output (r iso in figure 4-2 ) improves the feedback loops stability by making the output load resistive at higher frequencies; the bandwidth will usually be decreased. figure 4-2: output resistor, r iso stabilizes large capacitive loads. bench measurements are helpful in choosing r iso . adjust r iso so that a small signal step response (see figure 2-14 ) has reasonable overshoot (e.g., 4%). v 1 mcp6l9x r 1 v dd d 1 r 1 > v ss C (minimum expected v 1 ) 2ma r 2 > v ss C (minimum expected v 2 ) 2ma v 2 r 2 d 2 r 3 r iso v out c l mcp6l9x r f r g r n downloaded from: http:///
mcp6l91/1r/2/4 ds22141b-page 12 ? 2009-2011 microchip technology inc. 4.4 supply bypass with this family of operational amplifiers, the power supply pin (v dd for single supply) should have a local bypass capacitor (i.e., 0.01 f to 0.1 f) within 2 mm for good high-frequency performance. it also needs a bulk capacitor (i.e., 1 f or larger) within 100 mm to provide large, slow currents. this bulk capacitor can be shared with other nearby analog parts. 4.5 unused op amps an unused op amp in a quad package (e.g., mcp6l94) should be configured as shown in figure 4-3 . these circuits prevent the output from toggling and causing crosstalk. circuit a sets the op amp at its minimum noise gain. the resistor divider produces any desired reference voltage within the output voltage range of the op amp; the op amp buffers that reference voltage. circuit b uses the minimum number of components and operates as a comparator, but it may draw more current. figure 4-3: unused op amps. 4.6 pcb surface leakage in applications where low input bias current is critical, printed circuit board (pcb) surface leakage effects need to be considered. surface leakage is caused by humidity, dust or other contamination on the board. under low humidity conditions, a typical resistance between nearby traces is 10 12 ? . a 5v difference would cause 5 pa of current to flow; this is greater than this familys bias current at 25c (1 pa, typical). the easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). the guard ring is biased at the same voltage as the sensitive pin. figure 4-4 is an example of this type of layout. figure 4-4: example guard ring layout. 1. inverting amplifiers ( figure 4-4 ) and trans- impedance gain amplifiers (convert current to voltage, such as photo detectors). a) connect the guard ring to the noninverting input pin (v in +); this biases the guard ring to the same reference voltage as the op amps input (e.g., v dd /2 or ground). b) connect the inverting pin (v in C) to the input with a wire that does not touch the pcb sur- face. 2. noninverting gain and unity-gain buffer. a) connect the guard ring to the inverting input pin (v in C); this biases the guard ring to the common mode input voltage. b) connect the noninverting pin (v in +) to the input with a wire that does not touch the pcb surface. 4.7 application circuit 4.7.1 active low-pass filter the mcp6l91/1r/2/4 op amps low input noise and good output current drive make it possible to design low noise filters. reducing the resistors values also reduces the noise and increases the frequency at which parasitic capacitances affect the response. these trade-offs need to be considered when selecting circuit elements. figure 4-5 shows a third-order chebyshev filter with a 1 khz bandwidth, 0.2 db ripple and a gain of +1 v/v. the component values were selected using micro- chips filterlab ? software. resistor r 3 was reduced in value by increasing c 3 in filterlab. figure 4-5: chebyshev filter. v dd v dd ? mcp6l94 (a) ? mcp6l94 (b) r 1 r 2 v dd v ref v ref v dd r 2 r 1 r 2 + ------------------ ? = guard ring v in Cv in + r 1 v in v out r 2 3.01 k ? 6.81 k ? mcp6l91 c 1 120 nf r 3 9.31 k ? c 3 27 nf c 2 12 nf downloaded from: http:///
