amplifier circuit

Posted on Feb 4, 2014

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 4 © and 8 © loads. It has both short circuit and thermal protection, so is quite robust. With the addition of a handful of parts and a suitable power supply, this module will deliver over 50W RMS into 4 or 8 ohms with < 0. 1% Total Harmonic Distortion (THD) and < 0. 1% Intermodulation Distortion (IMD). A similar circuit was published in Elektor magazine, 11/96. It is also suitable as a replacement power amp stage, or upgrade for many existing amplifiers of between 30W-50W, provided they have a suitable dual supply, and most do.
