Description
Not Connected.
Ground.
Chip Select Input (Active Low). When CS returns high, data in the serial input register is decoded based on the address
bits, and then it is loaded into the target RDAC latch.
Preset to Midscale (Active Low). This pin sets the RDAC registers to 0x80.
Positive Power Supply. This pin is specified for operation at both 3 V and 5 V. It is the sum of |V
Terminal A Open-Circuit Shutdown (Active Low Input). This pin controls VR 1 through VR 4.
Serial Data Input. Data is input MSB first.
Serial Clock Input. This pin is positive edge triggered.
Serial Data Output. This pin is an open-drain transistor and requires a pull-up resistor.
Negative Power Supply. This pin is specified for operation at both 0 V and −2.7 V. It is the sum of |V
