8-BIT 3CH D-A CONVERTER WITH BUFFER AMPLIFIERS GENERAL DESCRIPTION The M62343P,FP is a CMOS 3 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.
