This is the 300W RMS stereo power amplifier circuit project. This amplifier is based four pieces of power IC TDA7294. It’s mean that every single channel of the circuit uses two ICs in bridge mode. In this application, the load value must not be less than 8 Ohms.

The main advantages of this solution are the following:
– 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 of ± 25V, the maximum performance that can be obtained is 150 W per channel. While with 16 Ohms load, and a power supply voltage of ± 35V, we will have a maximum of 170 W per channel.

This 300W RMS stereo power amplifier require symmetrical power supply to work, the circuit diagram is included in this post.

2. TDA7294 is a monolithic class AB audio amplifier with a DMOS output stage. Firstly, it is used in Hi-Fi field applications for amplification of audio signals which includes self-powered loudspeakers, TV, etc. Secondly, it has its own fault protection circuitry against short-circuits and provides a thermal shutdown.
3. TDA7294 is a monolithic integrated circuit in Multiwatt15 package, with high output power (up to 100W) intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV).
