Description

The M62393P/FP 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 sink and source drive capacity of 1.0 mA

or more, and it operates in the whole voltage range from VrefU to ground. And because of connects maximum 8 pieces

to 64 channels control.

Features

• Output buffer operational amplifier

It operates in the whole voltage range from VrefU (0 to 5 V) to ground.

• High output current drive capacity: ±1.0 mA 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-monitor or CTV.
