One Chip AM/FM Radio with Audio Power Amplifier
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. D AFC-connection for VHF-tuner D AM-FM switching without high frequency voltages
Features
D Large supply voltage range VS = 3 to 12 V D High AM-Sensitivity D Limiting threshold voltage Vi = 50 mV D Audio output power P0 = 0.7 W
Applications
D AM-/FM- and audio-amplifier
