The post 50W Power Amplifier with IC TDA7294 first appeared on Electronic Schematic Diagram.]]> 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.

Components List:

R1_____________ 150R
R2, R3, R5_____ 10K
R4_____________ 680R
R6_____________ 22K
IC1____________ TDA 7294
Heatsink
 
C1____________ 1u5F or 1u
C2____________ 2n7F
C3, C6________ 22uF 63V
C4, C5________ 10uF 63V
C7, C9________ 2200uF 50V
C8, C10_______ 100nF

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.

Suggested power supply for this audio amplifier:

35V Symmetrical Power Supply
