Product Introduction

Overview

The TPA3251D2DDVR is a high-performance class-D power amplifier produced by Texas Instruments. This device is designed to deliver true premium sound quality with the efficiency of class-D technology. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction known as PurePath™ Ultra-HD, which ensures ultra-low distortion across the audio band and superior audio quality.

The amplifier can drive up to 2 x 175 W into 4-Ω loads and 2 x 220 W into 3-Ω loads, and it supports multiple configurations including stereo, mono, 2.1, and 4xSE. It also boasts high power efficiency and very low power stage idle losses below 1 W, achieved through the use of 60 mΩ MOSFETs and an optimized gate driver scheme.
