5W Stereo Audio Amplifier

In this article, we are Going to reveal your ways you may build A 5W Stereo Audio Amplifier the use of TEA 2025 IC. We’ve Used Potentiometers For Left And right volume Controls. It Has energy Output is two.5 Watts at the Left And Right Channels. It Used nine to 12 Volts strength deliver For each Channels.

Circuit and running
Circuit Diagram Of 5W Stereo Audio Amplifier Is Given below. This Circuit Is built around IC TEA 2025. Two 10-Kilo-Ohm Potentiometers are also a part of This Circuit, eight-Ohm, 2.5 Watts Loudspeakers, And a few different additives Are parts Of This Audio Amplifier. This Amplifier Is high-quality to use together With a few speakers To Get Sound on your computer pc Or pc computer.

This Circuit provides The maximum advantage Of 45 DB but it is able to Be lowered with the aid of putting An outside RC collection Circuit between The Feedback Pin (6 And eleven As proven In Circuit Diagram) And ground. The functions Recommend That not reduce The gain beneath 36 DB. On the way to advantage maximum end result, Use R=0 And C=100 ΜF between The comments And floor. Frequency method Is Given under To Calculate The Frequency.

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

A high-quality feature Of TEA2025 Is It Has integrated Thermal safety. Its complete capacity Is five Watts in case you want To Run It On full Output. As a way to benefit complete Output, you may Use warmth Sink within the Circuit. In case you Don no longer Use warmth Sink inner Thermal safety Will no longer permit The IC To harm it’ll lessen The Output power while it’s going to feel immoderate energy.
