7.3.1 Fully-Differential Amplifier

The TRF1208 is a voltage-feedback fully differential amplifier (FDA) with a fixed gain by architecture. The TRF1208 operates best as a single-ended to differential amplifier by terminating the INM pin with a 50‑Ω resistor and driving the INP pin directly with no external components.

This amplifier has nonlinearity cancellation circuits that provide excellent linearity performance over a wide range of frequencies.

The output of the amplifier has a low dc impedance. Therefore, if required, the output of the amplifier can be matched to a load if required by adding the appropriate series resistors or attenuator pad.
