TPA3255 Bluetooth High Power Vertical Digital Power Amplifier 300W + 300W
Product description:
The TPA3255 is a high-performance class D power amplifier chip with class D efficiency and a circuit that delivers truly high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath ™ ultra-high definition). This technology allows the device to maintain ultra-low distortion over the entire audio band while exhibiting sound quality. The device operates in AD mode, capable of driving up to two 315W/4R loads and two 150W (unclipped power)/8R loads at 10% THD, and features a 2 VRMS analog input interface that supports seamless connection with high-performance DACs (e.g. TI's PCM5242). In addition to excellent audio performance, the TPA3255 also combines high power efficiency with ultra-low power stage idle loss (below 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme, which significantly reduces idle losses compared to traditional discrete implementations.
Product Specifications:
This machine is developed and produced according to standard products, and all parts are original and genuine.The tablet realizes wireless music playback with various portable products, and has a USB input port, which can be used as an external USB sound card to directly connect to computers and mobile phones to improve sound quality (cannot be plugged into a U disk to play). The machine is directly powered by a 220V power supply, which is convenient to use. The all-aluminum chassis is fine in workmanship and ensures good heat dissipation at the same time.
