40 Watt Audio power Amplifier LM3876
This Circuit is based on the LM3876. A 11-pin plastic package IC with high performance audio power amplifier, an output mute function which can be used to eliminate switch-on and switch-off "thumps" to the loudspeaker load. It is capable of...
Car Amplifier Circuit Schematic using TDA2040 Integrated Audio Amplifier
A car stereo amplifier circuit utilizing the TDA2040 is presented here. The TDA2040 is a monolithic integrated audio amplifier that functions in Class AB mode. This integrated circuit features built-in short circuit protection and thermal shutdown capabilities, and it can...
Audio Line Driver
The preamplifier described is engineered with a low output impedance, specifically designed to handle long cable runs. This feature allows for listening to a remote music source without the need for expensive screened cables. The preamplifier boasts a very low...
Small IC amplifiers for speakers
A small amplifier IC circuit has been compiled. This circuit is part of an older series and is categorized as a simple OTL (Output Transformer-Less) circuit.
The presented small amplifier IC circuit is designed for applications where compact size and simplicity...
Variable_audio_oscillator_with_a_range_of_20_hertz_to_20_kilohertz
A variable audio oscillator operates within a frequency range of 20 hertz to 20 kilohertz. The circuit utilizes an Intersil 8038 waveform generator, which is designed in a 14-pin dual in-line package (DIP).
The variable audio oscillator circuit is designed to...
Audio-oscillator
The circuit's frequency of oscillation is given by the formula: f = 2.8 / [C1 x (R1 + R2)]. By adjusting the potentiometer R2, the output frequency can be varied from 60 Hz to 20 kHz. A portion of the...
Fast Audio Peak Limiter
The circuit devised by Phil Allison still has some input voltage limitations, since it is based on a FET. Junction FET VCAs also create considerable distortion, with the worst of it appearing when the signal is attenuated by 6dB. The...
Simple Hybrid Audio Amplifier
The ongoing debate regarding the superiority of valves versus transistors is not the focus here. However, for those undecided, this simple amplifier serves as an excellent test. It employs a valve as a pre-amplifier and a MOSFET in the output...
