2.2.1.6
Differential analog signals into the CS3301A/02A amplifiers are required to be biased to the center of the
power supply voltage range, which for bipolar supplies is near ground potential. Resistors to create the
common mode bias are selected based on the sensor impedance and may need to be modified from the
CRD5378 defaults depending on the sensor to be used. Refer to the recommended operating bias con-
ditions for the selected sensor, which are available from the sensor manufacturer.
