Description:

【Design】: TPA3255 is a high performance Class D power amplifier chip with Class D efficiency and a circuit that can bring true high end sound quality.
【Feature】: The device features an advanced integrated feedback design and proprietary high speed gate driver error correction. This technology allows the device to maintain low distortion across the entire audio frequency band while demonstrating sound quality.
【Detail】: The Car Amplifier Board operates in AD mode and can drive up to 2 315W/4R loads and 2 150W (unclipped power)/8R loads at a THD of 1.5%, and has a 2VRMS analog input interface to support stable performance DAC (such as TI's PCM5242) seamless connection.
【Function】: In addition to audio performance, the TPA3255 combines high power efficiency with low power level idle losses (less than 2.5W). This is achieved with 85mR MOSFETs and an optimized gate driver scheme.
【Size】: 122mmx73mmx30mm/48.03inx2.87inx1.18in
