Description TPA3255 is a high-performance Class D power amplifier chip, which has Class D efficiency and can bring true high performance A circuit with high audio quality. The device TE has advanced integrated feedback design and proprietary high-speed gate driver error correction function( PurePath Ultra High Definition. This technology allows the device to maintain ultra-low distortion throughout the entire audio frequency band, Simultaneously showcasing sound quality. This device operates in AD mode and can drive up to 2 315W/4Rs at a of 1.5% Load and two 150W (unshipped power)/8R loads, with te having a 2VRMS analog input interface, Supports seamless connection with high-performance DACs (such as TIs PCM5242). In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle loss (below 2.5W). This can Implemented through 85mR MOSFET and optimized gate driver scheme. This scheme is relative to traditional segmentation Implementing a solution can significantly reduce idle loss. The 2023 enhanced version adopts excellent circuit design and high-quality components, thus ensuring performance. It can work stably under DC 52V, and passed the 60V high-voltage test during laboratory testing. To sound quality, The TPA3255 adopts a differential input structure, and the operational amplifier adopts a TL072 operational amplifier with field effect input, providing warm sound quality, The input adopts HIFI tantalum capacitor, which is delicate and natural. The is a Japanese chemical or with a withstand voltage of up to 63V Capacitors safety. The output adopts a lossless inductor and a high current capacitor. Output increased by 1 A 5V terminal can be used as a backup for external devices such as Bluetooth and players.
