TPA3251 4ch

PurePath™ Ultra-HD

Class D Audio Amplifier

 

Overview

EAUMT-0100-4-A is a 4 channel (BTL) high quality class D audio amplifier module base on TPA3251 with customized design and mainly suit for both consumer and professional project.
TPA3251 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 135 W into 4-Ω load and 2 x 175 W into 3-Ω load.
In addition to excellent audio performance, TPA3251 achieves both high power efficiency and very low power stage idle losses below 1 W. This is achieved through the use of 60 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.
