TDA2052 60 Watt Amplifier with Mute and St-By Functions

Figure 1 

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 functions so it can be controlled by external digital circuits. Very high temperature and output short circuit protections are included. You should use a heatsink to dissipate the excess heat.
