Sure Electronics AA-JA31181 | DSP | Amplifier Module

The Sure Electronics AA-JA31181 is a compact and powerful Class D audio amplifier board, designed to deliver 100 watts of clean, single-channel audio power. This booster module is an ideal solution for upgrading sound systems in portable speakers, DIY audio projects, or commercial installations where space is at a premium but high-quality output is essential. Its efficient design makes it particularly suitable for battery-powered applications, ensuring extended playback without compromising on performance.

At the heart of this amplifier lies the Texas Instruments TPA3116 chipset, a trusted topology known for its reliability and sound clarity. With an 88 dB signal-to-noise ratio, the board ensures low-noise operation, allowing your audio to remain crisp and free from unwanted interference. The amplifier achieves an impressive 84% efficiency, minimising heat generation and reducing the need for bulky heatsinks. It operates with a gain of 26 and can drive speakers with a minimum impedance of 2 ohms, delivering its rated 100 watts into a 4-ohm load. Connection is straightforward via 4-pin PCB connectors for both input and speaker output, while the board’s compact dimensions of 91 x 69 x 23 mm and mounting holes spaced at 84 x 61 mm make integration into your project simple and secure.
