TDA1083
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
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
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
Applications
D AM-/FM- and audio-amplifier
