TPA3255 Class D Digital Power Amplifier Board DC 24-48V 2.0 Channel Mini Digital Audio Stereo Amplifier PCB Board 300W + 300W for Audio System DIY Speakers NO5138

TPA3255 is a high-performance class D power amplifier, it has class D efficiency and can bring true high-end sound quality. In addition to excellent audio performance, it also features high power efficiency and ultra-low power level idle loss. With mini size and

high power, it\'s convenient in DIY installation and is practical to use.

Features:

It\'s a high-performance class D power amplifier with 2.0 channel, and can bring true high-end sound quality. Working voltage: DC 24-48V, recommended voltage 36V.

Features advanced integrated feedback design and proprietary high-speed gate driver error correction function. This technology allows the device to maintain ultra-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/4Ω loads and 2 150W (unclipped power)/8Ω loads, and has a 2 VRMS analog input interface that supports high-performance DAC seamless connection.

With high power efficiency and ultra-low power level idle loss (＜2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation, this solution can significantly reduce idle loss.

PCB board size: 110 * 70 * 35mm. Small size, 300W + 300W high power, more convenient DIY installation.
