Mitsubishi M62392P, M62392FP Datasheet
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)
