1 / 8 page TDA1083 Rev. A2, 23–Feb–01 1 (8) 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. 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 D AFC-connection for VHF-tuner D AM-FM switching without high frequency voltages Applications D AM-/FM- and audio-amplifier Figure 1. Block diagram and pin connections Absolute Maximum Ratings Reference points Pin 3 and 11, unless otherwise specified Parameters Symbol Value Unit Supply voltage range Pin 13 Vs 3 to 12 V Supply current when using the integrated stabilization circuit, VS = 12.5 to 14.3 V Pin 13 IS 50 mA Power dissipation Tamb = 65°C Ptot 600 mW Junction temperature Tj 125 °C Storage temperature range Tstg –25 to +125 °C Thermal Resistance Parameters Symbol Maximum Unit Junction ambient RthJA 100 K/W |
