MAS9184A

12 X 8-bit D to A Converter

• 12-bit serial data input

• Highly stable output buffer

• Serial data output for Daisy-Chaining

DESCRIPTION

The MAS9184 is a CMOS structured integrated

circuit with 12 built-in D to A converter channels and

12 corresponding output buffer operational

amplifiers. A simple 3-wire serial interface transfers

digital data from the micro controller. The output

buffers operate in the entire voltage range from

ground to the positive power supply rail.
