The Tiny Audio Amplifier kit utilizes the LM386 integrated circuit, which is designed for low voltage audio applications. The amplifier operates within a power supply range of 6 to 12 VDC, making it suitable for battery-powered devices. It delivers an output power of 1 watt into an 8-ohm load, which is adequate for driving small speakers or headphones.
The quiescent power drain of the amplifier is low, at only 24 mW when powered by a 6 VDC supply. This characteristic is advantageous for battery-operated applications, extending the operational life of the device. The output stage of the LM386 is designed to maintain a self-centering quiescent voltage, ensuring stable performance and minimal distortion in the audio output.
Volume adjustment is facilitated by an onboard PRESET potentiometer, allowing users to fine-tune the audio level according to their preferences. The circuit features terminal pins for easy connections to the power supply, audio input signal, and output speaker, promoting straightforward integration into various projects.
A power-on LED indicator is included to provide visual feedback when the amplifier is active, enhancing usability. The power supply is controlled by an ON/OFF PCB-mounted slide switch, enabling convenient operation.
The printed circuit board (PCB) measures 44 mm by 44 mm and includes four mounting holes, each with a diameter of 3.2 mm, allowing for secure installation in enclosures or projects. This compact design makes the Tiny Audio Amplifier kit an excellent choice for hobbyists and engineers seeking a simple yet effective audio amplification solution.The Tiny Audio Amplifier kit is a good choice for battery operation.
