INPUT SELECT
IN_SEL12IInput Selection with an internal 500-kΩ pullup and 320-kΩ pulldown resistor; selects input port. See Table 9-2.
AMPLITUDE SELECT
AMP_SEL1011IOutput amplitude swing select with an internal 500-kΩ pullup and 320-kΩ pulldown. See Table 9-3.
BIAS VOLTAGE OUTPUT
VAC_REF078OBias voltage output for capacitive coupled inputs. If used, TI recommends using a 0.1-µF capacitor to GND on this pin.
