Specifications, Features, Applications
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 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 V D High AM-Sensitivity D Limiting threshold voltage mV D Audio output power 0.7 W

Different dc voltages are developed at Pin 16 due to gain spread of AM-IF-amplifier. To determine the value of parallel resistance R8, at the output of the demodulator Pin 8 for V, AM mode without signal, dc voltage should be selected at Pin 16.
