The following schematic depicts the design of a for application using TDA1011 from Philips Semiconductor.


The TDA1011 is a monolithic integrated audio 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 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
