100 watts amplifier using tda7294:
This is a 100-watt amplifier using tda7294. we can use 20-0-20 voltage to 40-0-40 voltage and 5 amperes. we can get a maximum of 100 watts from bridge mode. in stereo mode, we can get 50 watts+50 watts. this is a mono-circuit diagram. we can get 100 watts with 4 ohms. We always have to use the best quality transformer to produce a good voltage. a good voltage can make good watts. tda7294 is a small IC but the output is the best.
Please use strong voltage. Always use the best quality transformer diode and capacitor to produce good voltage. here needs a minimum 2200uf and 50 voltage capacitor. the diode will be a minimum of 6 amperes. This board doesn’t have any output protection system. so needs speaker protection to protect the speaker. dual voltage and one input with one output.

Amplifier circuit diagram using stk4152:
This is an Amplifier circuit diagram using stk4152. this board can make 30 Watts + 30 Watts. We can use 20-0-20 voltage to 35-0-35 voltage. this is a stereo board. In this circuit, we can use STK 4141 to STK 4191. here need dual voltage. positive negative and ground voltage. Features
The (STK4152) series STK4102 and STK4101V series
(the high-grade type) are pin-consistent in the output range of 6W to 50W and enable easy diagrams.
The Small-sized package whose pin assignment is the same
as that of the STK4101 series
The Built-in muting circuit cut off many kinds of pop noise
The Greatly reduced heat sink due to the substrate temp is 125°C
The best cost performance.
