Build a power amplifier circuit using 2N3055 NPN transistors. The speciality of this circuit diagram is that the input working voltage is in a single supply. You can give the input DC voltage of 12v to 24 V. This 12…
Building a power amplifier is not an easy task, but in this post i would like to share the best bass boosting audio amplifier circuit with less external components. This audio amplifier is working based on the common TDA2030 audio…
Introduction Tda7297 is a dual bridge audio amplifier IC, and it can provide the output wattage of 15 watts per dual channel ( 15 watts + 15 watts). The amplifier IC is designed as bridge mode so the speaker impedance…
Introduction The class d amplifiers are the most efficient amplifiers to use on the car audio amplifier and also the home audio systems. So in this post i would like to share the very simple 10 watt class d amplifier…
Introduction This IC can be seen on Television, radio, and other electronic devices like radar. Guitar and keyboard instruments also use this small audio amplifier circuit. So in this circuit, I am going to give an idea about the TDA2822…
The amplifier circuit using TDA7851L 4 channel audio amplifier IC. This IC can able to deliver 48 watts per channel. The main advantage of this IC is about the working, the 12V single supply is enough to drive the Amplifier…
To keep your amplifier safe you need to provide a Cooling fan to control the temperature building upon it while working. Continuous working of cooling fans consumes a lot of energy and also makes some disturbing noise. To overcome this…
The Phono Preamp has a precise RIAA equalization curve and is very quiet and the best audio amplifier circuit you will ever get. Most of the people are building this secret circuit and do sales in the local market. Performance…
The amplifier circuit does not have any speaker protection circuit at the output stage so it is important to make sure the output connection is properly insulated before connecting the transformer power. Shorting the speaker output may lead to the…
