Jun 03, 2011
Description
The M62332/M62337 is an integrated circuit 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 1.0 mA
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.
Features

Output buffer operational amplifier: It operates in the whole voltage range from VCC to ground.
High output current drive capacity: 1.0 mA over
Application
Conversion from digital data to analog control data for home-use and industrial equipment.
Signal gain control or automatic adjustment of display-monitor or CTV.

Precaution for Use
Supply voltage terminal (VCC) is also used for D/A converter upper reference voltage setting. If ripple or spike is
input this terminal, accuracy of D/A conversion is down. So, when use this device, please connect capacitor among
CC to GND for stable D/A conversion.
V
This IC’s output amplifier has an advantage to capacitive load. So it’s no problem at device action when connect
capacitor (0.1 F Max) among output to GND for every noise eliminate.
Purchase of Renesas’s I2C components conveys a license under the Philips I2C Patent Rights to use these
components an I2C system, provided that the system conforms to I2C Standard Specification as defined by Philips.
