The TPA3255 is a high performance Class D power amplifier chip with Class D efficiency and a circuit that delivers true high-end sound quality. The device te has an advanced integrated feedback design and a proprietary high-speed gate driver error correction function. This technology allows the device to maintain ultra-low distortion across the audio band while delivering sound quality. The device operates in AD mode and can drive up to two 315W/4R loads and two 150W (uncut power)/8R loads at 1.5% , and te has a 2VRMS analog input interface that supports seamless connection to high-performance DACs, In addition to excellent audio performance, the TPA3255 also combines the benefits of high power efficiency and ultra-low power stage idle losses (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. This solution provides a significant reduction in idle loss compared to traditional discrete implementations.<br><br>Model Number:TPA3255 Compatible Audio & Video Equipment Style:Amplifier,player impedance:4-8Ω Output:300W+300W Type of power amplifire:HIFI AMP Support APP:NO Rated voltage:DC19-DC55 Colour:Black Material:plastic Size:136x73x30mm<br><br>Package Contents: 1 x Audio Sound Amplifier Board<br><br>Only the above package content, other products are not included.
