2X SAMP-200 HiFi Dual-Core TPA3255 Class D Stereo Amplifier Board — 2 Channel 600W+600W, TL072 OP

High-performance Class D stereo amplifier board built around the TI TPA3255 dual-core power stage, delivering studio-grade sound with Class D efficiency. The design uses an advanced integrated feedback topology and proprietary high-speed gate-driver error correction (PurePath Ultra HD) to keep distortion extremely low across the full audio band for true high-end sound quality. Operates in AD mode with rated outputs of 600WX2/2R, 300WX2/4 ohm and 200WX2/8 ohm. The board provides a 2 VRMS analog input for direct hookup to high-performance DACs (for example TI PCM5242) and includes TL072 OP on the input stage. Efficiency is boosted by 85mR MOSFETs and an optimized gate-driver scheme, resulting in very low idle power draw (less than 2.5W). This integrated solution achieves high power efficiency and noticeably lower standby losses compared with traditional discrete implementations.
