TPA3255 is a high performance class-D power amplifier that enables true premium sound quality with class-D efficiency.
It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD).
This technology allows ultra low distortion across the audio band and superior audio quality. The device is operated in AD-mode,
and can drive up to 2 x 315 W into 4-Ω load at 10% THD and 2 x 150 W unclipped into 8-Ω load and features a 2 VRMS analog input
interface that works seamlessly with high performance DACs such as TI’s PCM5242. In addition to excellent audio performance, TPA3255
achieves both high power efficiency and very low power stage idle losses below 2.5W. This is achieved through the use of 85 mΩ MOSFETs
and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
