EPAD

Exposed Pad. The exposed pad must be connected to DVSS (Pin 13).

1, 3, 5, 7, 9, 11

NC

Do Not Connect.

2

FILTDIGOUT

Unbuffered Amplifier Output In Series with a Resistor RF. Adding a capacitor between FILT and VDD or VSS

implements a low-pass filtering function. In read mode, this pin functions as a digital output.

4

DIGIN

Digital Input.

6

VNEG

Negative Amplifier Input (Inverting Input).

8

VPOS

Positive Amplifier Input (Noninverting Input).

10

VCLAMP

Set Clamp Voltage at Output.

12

VOUT

Buffered Amplifier Output. Buffered version of the signal at the FILT/DIGOUT pin. In read mode, VOUT is a

buffered digital output.

13, 14
