M62359P,FP

8-BIT 8CH D-A CONVERTER WITH BUFFER AMPLIFIERS

DESCRIPTION

The M62359 is a 8-channel 8-bit voltage output digital to analog
converter.
The M62359 includes data latch circuit and gain change circuit of
output amplifiers.
Input data is a easy-to-use three-wires serial interface.
It is able to cascading serial use with Do terminal.
Gain set up data change a case the each channel`s output
voltage range is change ,and each channel`s output voltage

FEATURES

•All channel includes gain change latch circuit with output
amplifiers.

•14-bit serial data input

•Built-in reset circuit

APPLICATION

Conversion from digital control data to analog control data

for home-use and industrial equipment.

Automatic adjustment by combination with EEPROM and

microcomputer(replacement of conventional half-fixed
resistor).
