简  介: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 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 Supply voltage range Pin 13 Supply current when using the integrated stabilization circuit, VS = 12.5 to 14.3 V Pin 13 Power dissipation Tamb = 65°C Junction temperature Storage temperature range Symbol Vs IS Ptot Tj Tstg Value 3 to 12 50 600 125 –25 to +125 Unit V mA mW °C °C Thermal Resistance Parameters Junction ambient Symbol RthJA Maximum 100 Unit K/W TELEFUNKEN Semiconductors Rev.
