M62359P,FP
8-BIT 8CH D-A CONVERTER WITH BUFFER AMPLIFIERS
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.
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.
