TPA3255TDDVRQ1 General Description

Elevate your audio experience with the TPA3255-Q1, a class-D power amplifier that redefines what's possible in terms of sound quality and efficiency. Utilizing cutting-edge feedback design and proprietary PurePath™ Ultra-HD gate driver error correction technology, this amplifier delivers pristine audio fidelity across the entire frequency spectrum. Capable of powering up to 315 W into a 4-Ω load and 150 W into an 8-Ω load, the TPA3255-Q1 ensures that your music is heard exactly as the artist intended. With a 2-VRMS analog input interface that seamlessly integrates with high-end DACs such as TI's PCM5242, this amplifier is the perfect choice for audiophiles seeking the ultimate listening experience. Not only does the TPA3255-Q1 deliver exceptional audio performance, but it also boasts remarkable power efficiency, with power stage idle losses below 2.5W. This efficiency is achieved through the use of advanced MOSFETs and a carefully optimized gate driver scheme, setting a new benchmark for class-D amplifier technology
