DIY audio amplifiers circuit diagram electronics projects and other related audio projects like : power amplifiers, audio systems, audio filters, vu meters, tone control, audio equalizers and more .
This 25 watt audio amplifier is based on LM1875 manufactured by National Semiconductor and can give a maximum power above 30 watts for an 8 ohms impedance (for a 30 volts double supply).
The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications.
This 25 watt audio amplifier is designed to operate with a minimum of external components. Device overload protection consists of both internal current limit and thermal shutdown.
This 10W audio amplifier circuit is designed using TDA2003 audio amplifier IC which is a simple and low power audio amplifier, that require few electronic components .
