8-BIT 2CH I2C BU S D -A CONVERTER WITH BUFFER A MPLIFIER
DESCRIPTION
The M62332/M62337 is an integrated circui
semiconductor of CMOS structure with 2 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
Vcc to ground.
The M62332 and the M62337 differ only in their slave
address.
