The TEA5764UK is a single chip electronically tuned FM stereo Radio with Radio Data System (RDS) and Radio Broadcast Data System (RBDS) Demodulator and RDS/RBDS decoder for portable application with fully integrated IF selectivity and demodulation. The Radio is completely adjustment free and only requires a minimum of small and low cost external c visit page. AM/FM Stereo Radio Circuit

Description: The integrated circuit TDA1083 includes, with exception  of the FM front end, a complete AM-/FM-radio-circuit  with audio power amplifier. An internal Z-diode  stabilizes the supply voltage at VS 13 V, which allows  with the aid of a resistor and a rectifier, the circuit to be  driven by a higher external supply voltage. Features: Large supply voltage range VS = 3 to 12 V High AM-Sensitivity Limiting threshold voltage Vi = 50 V Audio output power P0 = 0.7 W AFC-connection for VHF-tuner AM-FM switching without high frequency voltages Applications: AM-/FM- and audio-amplifier Circuit Diagram: Circuit diagram for One Chip AM/FM Radio with Audio Power Amplifier Datasheet for TDA1083:   Download
