TDA 1083 TELEFUNKEN Semiconductors Monolithic Integrated Circuit Description The integrated circuit TDA 1083 includes, with exception the supply voltage at VS [13V, which allows with the aid of the FM front end, a complete AM–/FM–radio–circuit of a resistor and a rectifier, the circuit to be driven by a with audio power amplifier. An internal Z–diode stabilizes higher external supply voltage. Applications: AM–/FM– and Audio–Amplifier Features D Large supply voltage range VS=3 ... 12V D Audio output power P0 = 0.7 W D High AM–Sensitivity D AFC–connection for VHF–Tuner D Limiting threshold voltage Vi=50 mV D AM–FM switching without high frequency voltages Figure 1 Block diagram and pin connections Absolute Maximum Ratings Reference points Pin 3 and 11, unless otherwise specifi
