M62353P中文资料

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 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.
