0 EPAD Exposed Pad. The exposed pad must be connected to DVSS (Pin 13). 1, 3, 5, 7, 9, 11 NC Do Not Connect. 2 FILT/DIGOUT 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. VSS Negative Supply Voltage. 13, 14 DVSS, AVSS Negative Supply Voltage. 15, 16 DVDD, AVDD Positive Supply Voltage. Rev.
