Description
General part information
TPA3255 Series
TPA3255-Q1 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-Q1 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.
