Mitsubishi M62398P Datasheet
8BIT 12CH I C 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)
