M62334FP

Preliminary Datasheet M62334P/FP, M62339P/FP R03DS0039EJ0500 8-bit 4ch I2C BUS D/A Converter with Buffer Amplifiers Rev.5.00 Jun 03, 2011 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 VCC to ground. The M62334 and the M62339 differ only in their slave address. Features  Digital data transfer format: I2C BUS serial data method  Output buffer operational amplifier It operates in the whole 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.
