M62392P,FP

8-BIT 12CH I2C BUS D-A CONVERTER WITH BUFFER AMPLIFIERS

GENERAL DESCRIPTION

The M62392P,FP is a CMOS 12-channel D-A converter

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 1.0mA , and

an output voltage range is nearly between ground and

VrefU.

Maximum 8 ICs can be connected to a bus by using three

chip-select pins, so that it is possible to handle up to 96

channels.

FEATURES

•

I2C-bus serial data method

•

Wide output voltage range

Nearly between ground and VrefU (0~5V)

•

High output current drive capability

over ±1.0mA

•

2 setting voltage ranges by dual input pins

for upper voltage references (VrefU1,U2)

Conversion from digital data to analog control data for both consumer and industrial equipment.

Gain control and automatic adjustment of DISPLAY-MONITOR or CTV.
