This wideband FDA requires external resistors for correct signal-path operation. When configured for the desired input impedance and gain setting with these external resistors, the amplifier can be either on with the PD pin asserted to a voltage greater than (Vs–) + 1.7 V, or turned off by asserting PD low. Disabling the amplifier shuts off the quiescent current and stops correct amplifier operation. The signal path is still present for the source signal through the external resistors.
The Vocm control pin sets the output average voltage. If left open, Vocm defaults to an internal midsupply value. Driving this high-impedance input with a voltage reference within the valid range sets a target for the internal Vcm error amplifier.
