MAS9186

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.
