In this article we areAMPLIFIER CRICUIT demonstrating how you can construct a 5W stereo sound intensifier utilizing TEA 2025 IC. We have utilized two potentiometers for left and right volume controls. It has control yield is 2.5 watts on the left and right channels. It utilized 9 to 12 volts control supply for every channel.

Circuit and working 

Circuit outline of 5W stereo sound speaker is given beneath.AMPLIFIER CRICUIT This Circuit is worked around IC TEA 2025. Two 10-kilo-ohm potentiometers are likewise part of this circuit, two 8-ohm, 2.5 watts amplifiers and a couple of different segments are portions of this sound enhancer. This enhancer is ideal to utilize together with certain speakers to get sound on your PC or Workstation.

This Circuit gives the most extremeAMPLIFIER CRICUIT addition of 45 dB however it very well may be brought down by setting an outside RC arrangement circuit between the criticism pin (6 and 11 as appeared in circuit chart) and ground. The highlights suggests that not diminish the increase under 36 dB. So as to increase most extreme outcome, use R=0 and C=100 µF between the input and ground. Recurrence recipe is offered underneath to figure the recurrence. Product - Tda1543 ,

FL = 1/(2? CRL) = 80 Hz

AMPLIFIER CRICUITAn astounding component of TEA2025 is it has worked in warm security. its full limit is 5 watts on the off chance that you need to run it on full yield. So to increase full yield you should utilize heat sink in the circuit. On the off chance that you wear not utilize heat sink inward warm assurance won't let the IC to harm it will decrease the yield control when it will detect over the top power.
