Amplifiers create heat when they are in use and this heat can hurt how well they work and how long they last. To solve this problem, a special Temperature Controlled Fan Circuit for Audio Amplifiers has been made to keep the temperature just right. This circuit turns on the fan only when the amplifier gets […]

Subwoofer Low Pass Filter Circuit using Op-Amp TL062
A Subwoofer Low Pass Filter Circuit or LPF for short is an important electronic part that allows low frequency signals to pass through while reducing the strength of high frequency signals. This feature makes it especially useful in audio setups like subwoofers, which are made to deliver deep and powerful bass sounds. The circuit shown […]
Simple Car Stereo Amplifier Circuit using IC TDA1553
A car stereo amplifier is really important because it boosts the sound signals from the stereo system giving enough power to make the speakers work well. The circuit we are looking at uses the TDA1553 chip which is known for being a strong Class B amplifier. This chip is specially designed for car radios making […]
Designing a 24W Power Amplifier Circuit using IC TDA1516
The TDA1516 is a cool Class B power amplifier that comes in a 13 pin Single In Line (SIL) package. It is designed for many audio amplification jobs and has some great safety features like short circuit protection, thermal shutdown and protection against reverse polarity. When set up in a Bridge Tied Load (BTL) configuration, […]
