The TDA1001B is a monolithic integrated circuit for suppressing interference and noise in FM mono and stereo receivers.

Features

• Active low-pass and high-pass filters

• Interference pulse detector with adjustable and controllable response sensitivity

• Noise detector designed for FM i.f. amplifiers with ratio detectors or quadrature detectors

• Schmitt trigger for generating an interference suppression pulse

• Active pilot tone generation (19 kHz)

• Internal voltage stabilization
