TPA3255 Class D Digital Power Amplifier Board DC 24-48V 2.0 Channel Mini Digital Audio Stereo

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/4 Ohm loads and 2 150W (unclipped power)/8 Ohm 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 ( less than 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.
