• 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.

FEATURES

• Eight 8-bit DACs on a single monolithic chip

• Voltage level output

• TSSOP 16 package

• Single +2.7V supply

• Power-on reset

BLOCK DIAGRAM

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.
