1 VDD Positive Power Supply. This pin should be decoupled with 0.1μF ceramic capacitors and 10 μF capacitors. 2 A Terminal A of RDAC. GND ≤ VA ≤ VDD. 3 W Wiper terminal of RDAC. GND ≤ VW ≤ VDD. 4 B Terminal B of RDAC. GND ≤ VB ≤ VDD. 5 GND Ground Pin. 6 PD Push-Down Pin. Connect to the external push button. Active high. An internal 100 kΩ pull-down resistor is connected to GND. 7 PU Push-Up Pin. Connect to the external push button. Active high. An internal 100 kΩ pull-down resistor is connected to GND. 8 ASE Automatic Save Enable. Automatic save enable is configured at power-up. Active low. This pin requires a pull resistor connected between VDD or GND. If ASE is enabled, this pin also indicates when the end scale (maximum or minimum resistance) has been reached. EPAD Exposed Pad. The exposed pad is internally floating. Rev.
