8-BIT 6CH D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62354 is an integrated circuit semiconductor of CMOS
structure with 6 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.
BLOCK DIAGRAM
APPLICATION
Adjustment/control of industrial or home-use electronic
equipment,such as VTR camera,VTR set,TV,and CRT
display.
