5W Audio Amplifier Circuit based BD139/BD140
The diagram illustrates a 5W audio amplifier circuit constructed using power transistors BD139 and BD140 for the final amplification stage. This compact amplifier serves as a general-purpose amplifier suitable for applications such as computer audio, radio, MP3 players, and video...
Class B audio amplifier
The closer the two transistors are matched, the better the performance. It is advisable to use TIP41 and TIP42 transistors, which are closely matched NPN and PNP power transistors with a dissipation rating of 65 watts each. If a TIP41...
9 volt headphone amplifier
The decision to design a 9V powered headphone amplifier has been finalized. The primary requirement was to power the circuit using a common PP3 (transistor radio) alkaline battery. The introduction of the 5534 low-noise op-amp at a reasonable price has...
MD1 audio w/ mCD & 32x buffer amp circuit
A program is needed to set the channels to their maximum level or to write the full scale to the Digital-to-Analog Converter (DAC). The MD schematics indicate that the audio signals are mixed with ratios of 0.0431 for the Programmable...
Audio amplifier 2X18W
In a lot of cars, the car radios use amplifiers that their output power does not exceed the 5W with enough distortion in the limits of power. The problem is tied with the utilization of external amplifiers, that will have...
Motional feed back amplifier
This versatile amplifier circuit was designed and submitted by Mr. Seetharaman Subramanian from Chennai. The original concept appeared in Practical Electronics, a UK-based magazine, and the circuit was finalized after extensive field trials and modifications between 1981 and 1986. Many...
