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
FEATURES

buffers operate in the entire voltage range from
ground to the positive power supply rail.
APPLICATION
Twelve 8-bit DACs on a single monolithic chip
Voltage level output
SO 20 package
Single +5V supply
Power-on reset
•
