M62393P/FP
8-BIT 8CH I C-BUS D-A CONVERTER WITH BUFFER AMPLIFIERS
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.
The input is 2-wires serial method is used for the transfer
format of digital data to allow connection with a microcomputer
with minimum wiring.
The output buffer operational amplifier employs AB class
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.
And because of connects maximum 8 pieces to 64 channels
FEATURES
•Digital data transfer format
I C-bus serial data method
•Output buffer operational amplifier
it operates in the whole voltage range from VrefU(0 to
5V)to ground.
•High output current drive capacity
±1.0mA over
•Preparation two high level reference voltage terminal
because there are two high level reference voltage
terminal,it can set up two kinds differ voltage range.
APPLICATION
Conversion from digital control data to analog control data
for home-use and industrial equipment.
Signal gain control or automatic adjustment of DISPLAY-
