termination resistors before ac-coupling capacitors on INPI and INPQ. The specifications refer
to one active channel with the other channel input terminated in 50
. The common-mode level for the gain control inputs is 0.5 V. A
maximum gain setpoint of 1.0 refers to a differential gain control voltage of 0.5 V.
