Class D TPA3255 HIFI Digital Amplifier Board Digit Power AMP Circuit Module 300W Multicolor

["brand new and high quality.\nDescription:\nThe TPA3255 is a high performance Class D power amplifier that offers Class D efficiency and delivers true high-end quality. The device features advanced integrated feedback design and proprietary high speed gate driver error correction.This technology allows the device to maintain ultra-low distortion throughout the band while delivering a perfect sound quality. The device operates in AD mode and can drive up to two 315W/4R loads and two 150W (unclipped power)/8R loads at a THD of 10%, and features a 2 VRMS analog input interface to support high performance DACs (For example, TI's PCM5242) Seamless connection. In addition to excellent performance, the TPA3255 combines high power efficiency with ultra-low power level idle loss (less than 2.5W). This can be achieved with a 85mR MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation, this scheme can significantly reduce the idle loss.\n\nFeatures:\nThe main filter electrolytic capacitor adopts the capacity of 4700UF/63V*2 to ensure strong and continuous power support.\nThe resistor uses high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine.\nUse special inductor to ensure the sound is crisp and powerful.\nPCB adopts double-sided sheet and tin-spraying process to ensure good passing performance of large and small currents.\n\nSpecifications:\nWorking method: Class D\nQuiescent current: 60mA\nWork efficiency: >90%\nOutput Power:\n315W/4Ω, distortion 10%\n185W/8Ω, distortion 10%\n260W/4Ω, distortion 1%\n150W/8Ω, distortion 1%\nFrequency response: 20Hz to 20KHz\nDynamic range: >100 dB\nSignal to noise ratio: (SNR) > 111dB\nWorking voltage: DC48V\nMaterial: Metal\nDimension: approx.149x93mm/5.87x3.66in\nColor: As pictures shown\nQuantity: 1 Pc\n\nNote:\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.
