The following schematic depicts the design of a 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. It features: high input impedance, high output power, low current drain and limited noise behavior at radio frequencies. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 ? load impedance.

List of electronics components are as follows:

C1 = 1 Micro Farad
C2 = 1 Micro Farad
C3 = 100 Pico Farad
C4 = 100 Nano Farad
C5 = 1.8 Nano Farad
C6 = 150 Nano Farad
C7 = 100 Micro Farad
C8 = 100 Nano Farad

C9 = 10 Micro Farad
C10 = 680 Micro Farad

R1 = 330 Kilo Ohm
R2 = 5.6 Kilo Ohm
R3 = 4.7 Ohm
RL = 4 Ohm
