MITSUBISHI M62398P,FP 8BIT 12CH I 2C BUS D–A CONVERTER WITH BUFFER AMPLIFIERS GENERAL DESCRIPTION The M62398P,FP is a 12V type CMOS 12-channel D–A converters with output buffer amplifiers. It can communicate with a microcontroller via few wiring thanks to the adoption of the two-line I2C BUS. The output buffer amplifier employs AB class output with sinking and sourcing capability of more than 2.5mA ,and an output voltage range is nearly between ground and VrefU. Maximum 8 ICs can be connected to a bus by using three chip-set pins , so that it is possible to handle up to 96 channels. FEATURES I2C BUS serial data method Wide output range Nearly between ground and VrefU(0~12V). High output current drive capability Over ±2.5mA 2 setting voltage ranges by dual input pins for upper voltage references (VrefU1,U2) APPLICATION Conversion from digital control data to analog control data for both consumer and industrial equipment. Gain control and automatic adjustment of DISPLAY-MONITOR or CTV.
