Dual Audio Power Amplifier

General Description:
The TA8211AH is dual audio power amplifier for consumer applications.  This IC provides an output power of 6 watts per channel  (at VCC = 20 V, f = 1 kHz, THD = 10%, RL = 8 Ω).  It is suitable for power amplifier of TV and home stereo. 
Features: High output power: Pout = 6 W/channel (Typ.)  (VCC = 20 V, RL = 8 Ω, f = 1 kHz, THD = 10%)  Low noise: Vno = 0.14 mVrms (Typ.)  (VCC = 28 V, RL = 8 Ω, GV = 34dB, Rg = 10 kΩ,  BW = 20 Hz~20 kHz)  Very few external parts  Built in thermal shut down protector circuit  Operating supply voltage range: VCC (opr) = 10~30 V (Ta = 25°C)

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: Large supply voltage range VS = 3 to 12 VHigh AM-SensitivityLimiting threshold voltage Vi = 50 VAudio output power P0 = 0.7 WAFC-connection for VHF-tunerAM-FM switching without high frequency voltages
Applications: AM-/FM- and audio-amplifierCircuit Diagram:
