10w audio amplifier circuit schematic

The circuit consists of a series of dual power supplies, providing a symmetrical ±15V supply for linear circuits. The same principle is applicable to non-symmetrical supplies, such as 5.0V and -12V regulators, which are used in applications like registers....

The Zener diode functions as an avalanche rectifier in reverse bias mode, connected to the input circuit of a wideband RF amplifier. The noise is amplified and subsequently applied to the cascade wideband amplifier, utilizing transistors Q2 and Q3. The...

The original description discusses an application that is reputed for its high-quality sound. This superior sound quality is attributed to the operation of the entrance transistors at Class A. The sound quality is largely dependent on IC1, which needs to...

Logic power control of an analog regulator can be useful in applications where a digital circuit or controller needs to manage a power source, such as in EEPROM programmers or other power control systems. This circuit provides ON-OFF control...

This simple circuit employs a 741 operational amplifier (op-amp) in differential mode to function as a continuity tester. The voltage difference between the non-inverting and inverting inputs is amplified by the full open-loop gain of the op-amp. Initially, ignore...

A simple function generator that produces a specific frequency. While awaiting the arrival of the AD9832 chip, a basic version of a Direct Digital Synthesis (DDS) synthesizer was developed using only the AT2313 microcontroller and a resistor network. This...
