Circuit audio amplifier TDA2040 base circuit

single electronic scheme 
Description 30 Watt audio amplifier  circuitry:. A 30-watt audio amplifier circuitry using TDA2040 is shown  here. TDA2040 is a monolithic class AB audio integrated amplifier available in Pentawatt package  The IC: has a low harmonic distortion, cross low is distortion and : has a built in protection circuitry for short circuit.  In the circuitry of two TDA2040 ICs are wired in BTL (Bridge Load tie) configuration to Provide 30W output in one 8 ohm speaker to + / -16V DC.  The capacitor C1 is the input DC decoupling capacitor.  Network comprenant components R2, C4, R3 Provides feedback to IC1 while R7, C6, R8 Network Provides information to the IC2. Network C5, C9 and R5, R9 Provides high frequency stability.  The C2, C3 filters the positive supply rail while the capacitors C7, C8 filters the negative supply rail.

 Notes:. A well-designed and good quality PCB Will Always Improve the sound  
 
quality. Use the + / -16V DC dual power supply to the power  
amplifier. Heat sinks are needed to IC1 and IC2  
Loads can be a speaker 8 ohms.  
C2 , C7 shoulds be Evaluated 25V electrolytic and others May be 10 or 15V.
