8-BIT 2CH D-A CONVERTER WITH BUFFER AMPLIFIERS
GENERAL DESCRIPTION
The M62342P,FP is a CMOS 2 channel D-A converter
with output buffer amplifiers.
It can communicate with a microcontroller via few wiring
thanks to the adoption of the three-line DI,CLK,LD.
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
Vcc.
FEATURES
• 10bit serial data input (3-wire serial transfer method)
• Wide output voltage range
Nearly between ground and Vcc(0 to 5V)
• High output current drive capability
over ±1.0mA

Shift clock input terminal. Input signal at DI pin is input to 10-bit shift register at
rise of shift clock pulse.
When H-level signal is input to this terminal,the value stored in 10-bit shift
register is loaded in decoder and D-A converter output register.
