One Chip AM/FM Radio with Audio Power Amplifier

Leave a Comment
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
