MITSUBISHI<Dig.Ana.INTERFACE> M62359P,FP 8-BIT 8CH D-A CONVERTER WITH BUFFER AMPLIFIERS PIN CONFIGURATION (TOP VIEW) 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.
