of built-in inverting type amplifier.
(replacement of conventional half-fixed resistor.)
M62381FP
8-BIT 8CH MULTIPLYING D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62381FP is an integrated circuit semiconductor of
CMOS structure with 8 channels of built-in 8-bit resolution
multiplication type D-A converters.
The input data is a easy-to-use 3-wire serial transfer method
and it is able to cascading serial use with Do terminal.
This device is capable of 4 quadrant multiplication because
FEATURES
•Digital data transfer method
3-wire 12-bit serial data transfer method(DI,CLK,LD)
•High pressure proof(VDD±5V)
•Short setting time
•Built-in reset terminal,all the buffer amplifier outputs
forces zero volts.
APPLICATION
Signal gain control of DISPLAY-MONITOR or CTV.
Conversion from digital control data analog control data
for form-use and industrial equipment.
Automatic adjustment by combination with EEPROM and
micro-computer.
