M62353P,FP,GP
8-BIT 8CH D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62353 is an integrated circuit semiconductor of CMOS
structure with 8 channels of built-in D-A converters with output
buffer operational amplifiers.
The 3-wire serial interface method is used for the transfer
format mum wiring.
It is able to cascading serial use with Do terminal.
The output buffer operational amplifier operates in the whole
voltage range from power supply to ground for both
input/output.
