Digital Ground.
Active Low Input. Terminal A open circuit. Shutdown controls Variable Resistor 1 through Variable Resistor 4.
Chip Select Input, Active Low. When CS returns high, data in the serial input register is decoded,
based on the address bits, and loaded into the target DAC register.
Serial Data Input.
Serial Data Output. Open drain transistor requires a pull-up resistor.
Serial Clock Input, Positive Edge Triggered.
Active Low Reset to Midscale. Sets RDAC registers to 80
Positive Power Supply. Specified for operation at both 3 V and 5 V.
