TDA1001BT
GENERAL DESCRIPTION
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
