M62393P Datasheet | Mitsubishi Electric

MITSUBISHI<Dig.Ana.INTERFACE> M62393P/FP 8-BIT 8CH I 2 C-BUS D-A CONVERTER WITH BUFFER AMPLIFIERS DESCRIPTION The M62393 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 microputer with minimum wiring. The output buffer operational amplifier employs AB class output circuit with sync and source drive capacity of 1.0m A or more,and it operates in the whole voltage range from Vref U to ground. And because of connects maximum 8 pieces to 64 channels control.
