OverviewThe TPA3255 is a high performance Class D power amplifier chip with Class D efficiency and a circuit that delivers true high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction. This technology allows the device to maintain ultra-low distortion over the entire audio frequency band while delivering 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 1.5%, and has a 2VRMS analog input connector to support seamless connectivity with high-performance DACs such as TI's PCM5242.
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.
