Overview
TDA1220B AM-FM QUALITY RADIO The TDA1220B is a monolithic integrated circuit in a 16-lead dual in-line package.
It is intended for quality receivers produced in large quantities.
The functions incorporated are: AM SECTION – Preamplifier and double balanced mixer – One pin local oscillator – IF amplifier with internal AGC – Detector and audio preamplifier FM SECTION – IF amplifier and limiter – Quadrature detector – Audio preamplifier The TDA1220B is suitable up to 30MHz AM and for FM bands (including 450KHz narrow band) and features: – Very constant characteristics (3V to 16V) – High sensitivity and low noise – Very low tweet ORDERING NUMBER : TDA 1220BK DIP-16 Plastic (0.
25) – Sensitivity regulation facility (*) – High recovered audio signal suited for stereo decoders and radio recorders – Very simple DC switching of AM-FM – Low current drain – AFC facility (*) Maximum AM sensitivity can be reduced by means of a resistor (5 to 12KΩ) between pin 4 and ground.
