60 Watt Amplifier using TDA2052

This is HiFi audio amplifier system. This amplifier is AB class amplifier and has very low distortion that's why this amplifier can be used for HiFi audio system. 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.

Functions of the Components:

1. R1 - Input Impedance
2. R2,R3 - Gain (32dB)
3. R4 - Input Impedance in Mute Mode
4. R5 - Standby Transition Time
5. R8 - Output Frequency Balancing
6. R9,R10 - Discharge Resistors
7. C1 - Input Coupling Capacitor
8. C3 - Feedback Coupling Capacitor
9. C4 - Standby Transition Time
10. C5 - Output Frequency Balancing
11. C6,C7 - Supply Stabilizing Capacitors
12. C9,C10 - Supply Filter Capacitors
