8-BIT 12CH D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62352 is an integrated circuit semiconductor of CMOS
structure with 12 channels of built-in D-A converters with
output buffer operational amplifiers.
The 3-wire serial interface method is used for the transfer
format mum 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
•12bit 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.
