MITSUBISHI<Dig.Ana.INTERFACE> M62393P/FP 8-BIT 8CH I 2 C-BUS D-A CONVERTER WITH BUFFER AMPLIFIERS DESCRIPTION PIN CONFIGURATION (TOP VIEW) 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 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 VrefU to ground. And because of connects maximum 8 pieces to 64 channels control. FEATURES •Digital data transfer format I 2C-bus serial data method •Output buffer operational amplifier it operates in the whole voltage range from VrefU(0 to 5V)to ground. •High output current drive capacity ±1.0mA over •Preparation two high level reference voltage terminal because there are two high level reference voltage terminal,it can set up two kinds differ voltage range.
