This is 4 Watt Amplifier Circuit Diagram for portable radio application using TDA1011 from Philips Semiconductor.

The TDA1011 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 W load impedance. The device can deliver up to 6 W into 4 W at 16 V loaded supply in mains-fed applications. The maximum permissible supply voltage of 24 V makes this circuit very suitable for d.c. and a.c. apparatus, while the very low applicable supply voltage of 3,6 V permits 6 V applications.
