TPA3255 2ch

PurePath™ Ultra-HD

Class D Audio Amplifier

 





Overview

EAUMT-0260-2-A is a 2 channel (BTL) high quality class D audio amplifier module base on TPA3255 with customized design and mainly suit for both consumer and professional project.
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 315 W into 4-Ω load at 10% THD and 2 x 150W unclipped into 8-Ω load.
In addition to excellent audio performance, TPA3255 achieves both high power efficiency and very low power stage idle losses below 2.5 W. 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.
With improved design to obtain highest performance and lowest noise and distortion, this module provide an excellent audio solution that highly compact and efficiency with state-of-the-art performance.
