Terminal A of RDAC2. V
Wiper Terminal of RDAC2. V
Terminal B of RDAC2. V
Positive Power Supply. Decouple this pin with 0.1 µF ceramic capacitors and 10 µF capacitors.
Logic Power Supply; 1.8 V to V
Serial Clock Line.
Serial Data Input/Output.
Programmable Address (ADDR1) for Multiple Package Decoding.
Programmable Address (ADDR0) for Multiple Package Decoding.
Linear Gain Setting Mode at Power-Up. Each string resistor is loaded from its associated memory location.
If INDEP is enabled, it cannot be disabled by the software.
Hardware Reset Pin. Refresh the RDAC registers from EEPROM. RESET is activated at logic low.
If this pin is not used, tie RESET to V
