**TDA7294 Amplifier Circuit Diagram RMS 300W**

This is TDA7294 RMS 300W Amplifier Circuit Diagram. This amplifier has four pieces of power IC TDA7294. That’s mean this circuit uses two IC’s of every single channel in bridge mode. Here load value must not be less than 8 Ohms.

Main advantages of this circuit:

* High power with low voltage.

* Considerable power, even at high load values (Up to 16 Ohm).

With a load of 8 Ohms and a power supply voltage ±25V max, the maximum performance that can be obtained is 150W per channel. While with 16 Ohms load, and a power supply voltage of ±35V, we will have a maximum of 170W per channel.
