Analog Ground
Digital Ground. Also Analog Ground for DIP package.
Supply Voltage
Active-Low Load DAC Input. Driving this asynchronous input low transfers the contents
of the input register to the DAC register.
Serial-Data Input
Serial-Clock Input. The serial input data is clocked in on SCLK’s rising edge.
Clear DAC Input. Clears the DAC register. Tie to V
