TPA3255 Audio Power Amplifier Board Powerful Sound Amplifier Speaker Amp Board 7W Amplificador Board

features integrated feedback design and proprietary high-speed gate driver error correction function. This technology allows the device to maintain low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device works in AD mode. When the THD is 10%, it can drive up to 2*315W/4R loads and 2*150W (unclipped power)/8R loads, and has a 2 VRMS analoginput interface that supports high-performances DAC seamless connection.

Features:

High power efficiency and low power level idle loss (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate drivervscheme.

Compared with the traditional discrete implementation, this solution can significantly reduce idle loss.

Adopt SAGAMI 7W14A inductor for audio digital class D amplifier to ensure the sound is clear and powerful.

Made of fine quality material for long service time.

Compact size and easy to use.
