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.

APPLICATIONS
• 3-pin Serial Data Interface
• Low Voltage Output Buffer
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.

... 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. ...
