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.

Function
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. 8bit D–A converter output terminal Power supply terminal GND
