Description

The TDA9901 is a wideband, low noise amplifier with differentialinputsandoutputs.TheTDA9901incorporates an AGC function with digital control.

The TDA9901 is optimized for fast switching between different gain settings, preserving small phase and amplitude error.

The TDA9901 presents an excellent combination of lownoise and good linearity for a wide input frequency range. The TDA9901 is optimized for processing IF signals in GSM base stations. It is also suited for many other applications as a general purpose digitally controlled variable gain amplifier.

The TDA9901 is able to operate from 4.75to5.25V supply for the analog part and from 3.0to5.25V for the digital part.
