www.DataSheet4U.com DA9184A.001 September 7, 1998 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.
