• Product Introduction:amplifier board is designed for the small space of modern digital products. Its miniature size contains powerful performance and can be easily integrated into various devices, becoming an invisible promoter of sound effect upgrade. Whether it is a compact laptop, portable speaker, or space-constrained LCD TV and monitor, it can perfectly adapt and release shocking sound effects. High efficiency:This audio amplifier board uses advanced D-type amplification technology with an efficiency of up to 90%, and can provide an impressive 3W (left channel) + 3W (right channel) output power even with a 4Ω load and a 5V power supply. This means it can provide a more powerful and clearer audio experience with lower energy consumption, significantly extending the battery life of the device. Not affected by temperature:The D-type power amplifier has a very high amplification efficiency, ensuring that the sound quality is not affected by temperature changes. Even under long-term operate or high load conditions, mini voice amplifier can maintain stable output without the need for an additional heat sink, avoiding the degradation of sound quality due to temperature rise, and ensuring the consistency and purity of the sound effect. Noise reduction circuit:The Mini Digital Power Amplifier Board has a built-in noise reduction circuit, which can effectively suppress noise at the moment of power on or off, ensuring clear sound without noise. At the same time, it supports short circuit, overcurrent and overheating protection functions, providing multiple layers of protection for the safe operate of the equipment, and can work stably even in complex environments to avoid potential circuit damage. Wide application:This amplifier board is suitable for a wide range of application scenarios, including but not limited to LCD TVs, monitors, laptops, portable speakers, DVD players, game consoles and mobile phones, etc. And audio amplifier board can be powered by computer USB 5V, mobile phone charger 5V or lithium battery.
