M62399P,FP
8-BIT 8CH I ²C-BUS D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62399P,FP is an integrated circuit semiconductor of
high voltage type 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
formal 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 2.5mA or
more,and it operates in the whole voltage range from VrefU to
ground.
And because of connects maximum 8 pieces,it is possible to
64 channels control.
FEATURES
•Digital data transfer format
I ²C-bus serial data method
•Output buffer operational amplifier
it operates in the whole voltage range from VrefU(0~12V)to
ground.
•High output current drive capacity
±2.5mA 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.
