Audio TPA3255 2.0 Digital Amplifier Board DC24-48V Strong High Power 300W 300W Class D Digital Amplifier Board
TPA3255 is a high-performance class D power amplifier with class D efficiency, which can bring true high-end sound quality.
The device has an advanced integrated feedback design and a proprietary high-speed gate driver error correction function (PurePath Ultra HD). This technology enables 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 two 315W/4R loads and two 150W (unclipped power)/8R loads. It has a 2VRMS analog input interface and supports high-performance DACs (such as TI's PCM5242) for seamless connection.
In addition to excellent audio performance, TPA3255 also has two major advantages: 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 traditional discrete implementations, this solution can significantly reduce idle losses.
