Description
Positive Supply Voltage.
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.
Digital Input.
Negative Amplifier Input (Inverting Input).
Positive Amplifier Input (Noninverting Input).
Set Clamp Voltage at Output.
Buffered Amplifier Output. Buffered version of the signal at the FILT/DIGOUT
pin. In read mode, VOUT is a buffered digital output.
Negative Supply Voltage.
Negative Supply Voltage.
Positive Supply Voltage.
Do Not Connect.
