APPLICATION
Conversion from digital control data to analog control data
Signal gain control of DISPLAY-MONITOR or CTV.
FEATURES
•All channel includes gain change latch circuit with output
•14-bit serial data input
•Built-in reset circuit
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.
voltage range is change ,and each channel`s output voltage
range is able to change severally make use of gain set up data.
for home-use and industrial equipment.
microcomputer(replacement of conventional half-fixed
resistor).
Gain set up data change a case the each channel`s output
Automatic adjustment by combination with EEPROM and
amplifiers.
