MAS9186
This is preliminary information on a new product under development. Micro Analog Systems Oy reserves the right to make any changes without notice.
8 X 8-bit D to A Converter
* 3-pin Serial Data Interface * Low Voltage Output Buffer
DESCRIPTION
MAS9186 is 8-channel 8-bit DAC, designed primarily for trimmer replacement. Device is controlled by a simple 3-line input. The output buffers operate in the entire voltage range from ground to the positive power supply rail. DAC is selected with three first bits in serial input data (SDI-pin) and the DAC output value is set according to the last 8 bits in serial input data.
FEATURES
* * * * * Eight 8-bit DACs on a single monolithic chip Voltage level output TSSOP 16 package Single +2.7V supply Power-on reset
APPLICATIONS
* * * High resolution monitors Automatic gain control Trimmer replacement

OPERATING MODES
DAC maximum output voltage is set using VREFH and VREFL pins (= 255/256 * (VREFH-VREFL)+VREFL) (note: VREFL=GND in case of MAS9186A1). XRESET pin is used for middle code preset: DAC registers are reset and middle code will appear at the DAC output. Serial input data is written to SDI while XCS is low. Data is read at CLK rising edge to on-chip shift register. Rising XCS-pin stops data reading and 11 CLK-cycles are used as the input data (3 address bits and 8 data bits). The last 11 bits before rising XCS are used as input data. Timing diagram
