M62334P_08

Manufacturer Part Number
M62334P_08
Description
8-bit 4ch I2C BUS D/A Converter with Buffer Amplifiers
Manufacturer
RENESAS [Renesas Technology Corp]
Datasheet
M62334P/FP, M62339P/FP
8-bit 4ch I
Description
The M62334/M62339 is an integrated circuit semiconductor of CMOS structure with 4 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 V
The M62334 and the M62339 differ only in their slave address.
Features
• Digital data transfer format: I
• Output buffer operational amplifier
• 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.
