Using a ±25v power supply can output up to 100w×2 THD approximately 0.1 at 8Ω (refer to the datasheet). Using a ±35v power supply may achieve higher power and lower THD, up to 150w×2. It is recommended to use a power supply of ±25v to ±30v (I personally use ±30v). It is suggested to use an AC dual 25v or 24v transformer. After rectification, the power will be approximately ±35v with a power of 300W. At least two 10000uf capacitors are needed for rectification (one for positive and one for negative) to ensure voltage ripple during high dynamic range.

The TDA7294 BTL power amplifier is a high-performance audio amplifier capable of delivering a maximum power output of 150 watts per channel. With a total output power of 300 watts, this amplifier is perfect for driving large speakers and creating a powerful sound system. The BTL (Bridge-Tied Load) configuration allows for increased efficiency and power output, making it ideal for use in home audio systems, professional sound reinforcement, and other applications where high-quality audio performance is essential. With its compact size and easy-to-use design, the TDA7294 BTL power amplifier is a versatile and reliable choice for those looking to enhance their audio experience.
