8-BIT 4CH I2C BUS D-A CONVERTER WITH BUFFER AMPLIFIERS 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. 0mA or more,and it operates in the whole voltage range from Vcc to ground. The M62333 and the M62338 differ only in their slave address.
