TPA3255 HIFI Digital Amplifier Board 300Wx2 (1 Set,Black) S2U1 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 features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra HD). This technology allows the device to maintain ultra-low distortion across the audio band while delivering sound quality.Operating in AD mode, the device can drive up to two 315W/4R loads and two 150W (unclipped power)/8R loads at 1.5% , and features a 2 VRMS analog input interface for seamless connection to high-performance DACs such as TIs PCM5242.In addition to excellent audio performance, the TPA3255 also combines efficiency and ultra-low power-level idle losses (less than 2.5W). This is achieved through an 85mR MOSFET and an optimized gate driver scheme.This solution provides a significant reduction in idle losses compared to traditional discrete implementations.Product parametersPower amplifier IC: TPA3255 chipInput : 3.5MM stereo wired socket interface (3PWork efficiency: 90%Output power: 315W/4?, distortion 1.5%; 185W/8?, distortion 1.5%; 260W/4?, distortion 1%, ; 150W/8?, distortion 1%2Frequency Response: 0Hz to 20KHzDynamic range: 100 dBSignal to Noise Ratio: () 111dBPower supply: DC19 to DC48V [current recommended above 5A]Overall size: 110 x 70 x 30MMMaterial: PCBcolour: BlackPackage Contents:1 x Amplifier Board Module1 x Audio cable
