TDA2052 is a AB class amplifier which operates with (+,-25V) supply and generates 60 Watt power (sound) output. Since it has very low distortion and it is a AB class amplifier, it can be used in HI-FI systems. TDA2052 has mute and st-by funcitons so it can be controlled by external digital circuits. Very high [...]
This is a stronger type. It features mute and stand-by functions, which require some additional discrete devices. The rest is just the common op-ampish and power-ampish stuff. I’ve never built this one, so I’ve got no suggestions concerning practical construction. Link
