M62356P
DESCRIPTION
The M62356P is an integrated circuit semiconductor of C-MOS
structure with 8 channels of built-in D-A converters.
The input data is a easy-to-use 3-wires serial data transfer
method and it is able to cascading serial use with Do terminal.
FEATURES
•Digital data transfer format
3-wires serial data transfer method
•Output voltage range 0V to 12V
•Short setting time
•D-A converter high level reference voltage is possess two input
terminal then two reference voltage is possible to input.
Digital voltage supply........................VDD=5V±10%
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).
Signal gain control of DISPLAY-MONITOR or CTV.
