TPA3225 HiFi 600W Stereo Amplifier Board, 2.0 Channel, DC19-48V Power

Product Description

The TPA3255 is a high-performance Class-D power amplifier chip that delivers high-end sound quality with Class-D efficiency. Equipped with advanced integrated feedback design and proprietary PurePath™ Ultra HD technology, it ensures ultra-low distortion across the full audio frequency spectrum. Experience superior audio quality while driving up to two 315W/4Ω loads and two 150W/8Ω loads at 1.5% THD. Its 2 VRMS analog input interface enables seamless integration with high-performance DACs like TI's PCM5242. In addition to its exceptional audio performance, the TPA3255 offers high power efficiency and ultra-low idle power losses, achieving less than 2.5W. This is accomplished through an optimal 85mΩ MOSFET and gate driver scheme, providing significant idle loss reduction over traditional discrete implementations.
