This is 2x1W stereo amplifier circuit based on single IC KA2209. IC KA2209 is an equivalent IC to the TDA2822, you can use TDA2822 if you can’t find KA2209. It is ideal for battery powered operation since the supply required for this circuit is 2V to 9VDC. Power output depends critically on speaker resistance &… Read More »
This is 1W stereo audio amplifier with LM386N. The output power is 1 watt for each channel, so it should be use two ICs of LM386N National Semiconductor for stereo channel. This circuit belongs to kitsrus.com and the kit is available there or at electronickits.com. This circuit only need 10mA current with best voltage supply… Read More »
This is the circuit diagram of 1W audio amplifier which use TDA7052 as the main component and other 5 pieces of components to support the main component. The ideal supply voltage of this circuit is about 6-12V and no heatsink required. The schematic is for mono audio channel, just build two similar circuit for stereo… Read More »
Schematic Diagram
In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.
In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
