Description
The M62353 is an integrated circuit semiconductor of CMOS structure with 8 channels of built-in D/A converters with
output buffer operational amplifiers.
The 3-wire serial interface method is used for the transfer format of digital data to allow connection with
microcomputer with minimum wiring.
It is able to cascading serial use with DO terminal.
The output buffer operational amplifier operates in the whole voltage range from power supply to ground for both
input/output.
Features
• 12-bit serial data input (3-wire serial data transfer method)
• Highly stable output buffer operational amplifier allow operation in the all voltage range from power supply to
ground.
Application
Adjustment/control of industrial or home-use electronic equipment, such as VTR camera, VTR set, TV, and CRT
display.
