Tda7294 Amplifier Circuit Pcb Layout

The supply voltage may lie between 12 V and an absolute maximum of 44 V. Construction of the amplifier on the printed-circuit board should be straightforward. The transistors as well as the IC must be fitted insulated on to a heat sink of about 2 k W. Use plenty of heat conducting paste. The supply line should be protected by a 3.15 A fuse. LM386 Audio Amplifier Circuit with PCB It was my first mini audio amplifier. Many people also use it. Because it’s easy to build and this IC always popular. And suitable for 9V battery. 2W+2W Stereo using 3 LM386 Here is an LM386 stereo audio amplifier circuit, 2 watts. Using 3 ICs in a bridge model.

This is a great audio amplifier circuit based on single power IC TDA7294. TDA7294 is intended for use as a high quality audio class AB amplifier in hi-fi applications. It has very low noise and distortion, wide bandwidth and good output current capability, enabling it to supply high power into both 4Ω and 8Ω loads. It has both short circuit and thermal protection, so is quite robust.
