It features an advanced integrated feedback design and proprietary high-speed gate driver error correction.This technology allows ultralow distortion across the audio band and superior audio quality.The device can drive up to 2 x 175 W into 4Ω load and 2 x 220 W into 3Ω load and features and 2Vrms analog input interface that works seamlessly with high performance DACs such as TIPCM5242. In addition to excellent audio performance, TPA3251 achieves both high power efficiency and very low power stage idle losses below 1W. This is achieved through the use of 60mΩ MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.SMPS unit and class D stage have perfect protection each, so the constant runningperformance well. class D stage have additional DCP/OCP protection, works stable at some worse conditions, input signal have hardware dynamic limiter and support balance signal input, very better S/ N performance .The SINEWAVE G3H module is EMC and safety approved and the "black-box" completeness allows for fast designing and minimized time to market.Fixed BTL setting, user can not change working mode, due to better protection under BTL mode than SE mode and PBTL mode.Key BenefitsVERY QUIET BACKGROUND,VERY HIGH SOUND LEVEL.A wide set of features for plug and play implementation into Hi-Fi applications.Black-box design, module have good heat dissipation and better EMC performance.Advanced protected function against short circuits, overload and overheating and includes on-board fuses and EMI filtering that provide a CE and FCC pre-approved design.
