Here is the diagram of a 25 Watt poweramplifier circuitmade of TDA2009 IC. TDA2009 IC is a hi-fi Class AB stereo amplifier in a multi watt package. It is actually a dual audio power amplifier that is designed specifically for very good quality stereo applications. TDA2009 is used in amp...
At that time, I became very interested in amplifier circuits because almost everyone likes to listen to music. The first circuit I got was a car’s radio tape player. But I can’t turn on the music too loud because my mother doesn’t like it, and I want her to be comfortable, so ...
The circuit diagram of a two stage single ended Class A power amplifier is shown above. R1 and R2 are the biasing resistors. They form a voltage divider network which supplies the base of the transistor with a voltage 0.7V higher than the “negative maximum amplitude swing” of the input s...
2N3055 Power Amplifier Simple and low cost. The optimal supply voltage is around 50V, but this amp work from 30 to 60V. The maximal input voltage is around 0.8 - 1V. As you can see, in this design the components have a big tolerance, so you can build it almost of the components, ...
