In addition to excellent audio performance, the TPA3255 combines high power efficiency with ultra-low power stage idle loss (less than 2.5W). This is achieved through an 85mR MOSFET and an optimized gate driver scheme. This solution significantly reduces idle losses compared to traditional discrete implementations.
This product uses excellent circuit design and high-quality components, so the performance is guaranteed to work stably at 52V DC, and passes the 60V high-voltage test in the lab. In order to ensure the sound quality, TPA3255 adopts differential input structure, the op-amp adopts TL072 op-amp with field effect input, the sound quality is warm, and the input adopts HIFI tantalum capacitors, which is delicate and natural. The main filter is up to 63V voltage resistant Japanese chemical or Nikon capacitors, safety is guaranteed. The output adopts lossless red ring inductor and CBB high current capacitor. The output adds 1 5V terminal, which can be used as a spare for Bluetooth, player and other external devices.
