FEATURES
•Digital data transfer format
•Output buffer operational amplifier
•High output current drive capacity
•Preparation two high level reference voltage terminal
DESCRIPTION
The M62393 is an integrated circuit semiconductor of
CMOS structure with 8 channels of built-in D-A converters
with output buffer operational amplifiers.
format of digital data to allow connection with a microcomputer
with minimum wiring.
output circuit with sync and source drive capacity of 1.0mA or
more,and it operates in the whole voltage range from VrefU to
ground.
control.
APPLICATION
Conversion from digital control data to analog control data
because there are two high level reference voltage
terminal,it can set up two kinds differ voltage range.
for home-use and industrial equipment.
MONITOR or CTV.
I C-bus serial data method
it operates in the whole voltage range from VrefU(0 to
5V)to ground.
±1.0mA over
The input is 2-wires serial method is used for the transfer
The output buffer operational amplifier employs AB class
And because of connects maximum 8 pieces to 64 channels
