M62363FP

8-BIT 8CH D-A CONVERTER

DESCRIPTION

The M62363FP is an integrated circuit semiconductor of CMOS
structure with 8 channels of buil-in 8-bit multiplication type D-A
converters.
The input data is a easy-to-use 3-wire serial method and it is able
to cascading serial use with Do terminal.
The device is suited for use in automatic adjustment combination

FEATURES

•Digital data transfer method
3-wire serial data transfer method

•D-A converter system
Employment of the additional higher-order segment R-2R method
doubled precision compared to the convertional R-2R method.

•Short setting time

•4 Quadrant multiplication

APPLICATION

Convertion 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.)
