The M62358 is a 12-channel 8-bit voltage output digital to analog
converter.
The M62358 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
range is able to change severally make use of gain set up data.
Signal gain control of DISPLAY-MONITOR or CTV.
