GND

Positive Power Supply. This pin should be decoupled with 0.1µF ceramic capacitors and 10 µF capacitors.

Terminal A of RDAC. GND ≤ VA ≤ VDD.

Wiper terminal of RDAC. GND ≤ VW ≤ VDD.

Terminal B of RDAC. GND ≤ VB ≤ VDD.

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.
