3.2 Optional VCM Connection

The EVM includes an optional connection to set the common-mode voltage to the input of the device. Footprints of R25 and R26 are available to be used in a voltage divider with the positive supply voltage, VCC, as the input voltage. The resistor values will determine the output voltage or reference voltage that will set the input common-mode voltage.
