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.
