General description
The TDA9901 is a wideband, low-noise amplier with differential inputs and outputs. The
TDA9901 incorporates an Automatic Gain Control (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 low noise and good linearity for a wide
input frequency range. The TDA9901 is optimized for processing Input Frequency (IF)
signals. It is also suited for many other applications as a general purpose digitally
controlled variable gain amplier.
The TDA9901 is able to operate from 4.75 V to 5.25 V supply for the analog part and from
3.0 V to 5.25 V for the digital part.
