3 Description
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 can drive up to 2 x 325 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 3 W. This is
achieved through the use of 85 m
Ω MOSFETs and
an optimized gate driver scheme that achieves
significantly lower idle losses than typical discrete
implementations.
