TAS3251 is a digital-input, high-performance Class-D audio amplifier that enables true premium sound quality with Class-D efficiency. The digital front-end features a high-performance Burr-Brown™ DAC with integrated DSP for advanced audio processing, including SmartAmp and SmartEQ. The first high-power single-chip solution reduces overall system solution size and cost. The DSP is supported by TI PurePath™ Console Graphical tuning software for quick and easy speaker tuning and control. The Class-D power stage features advanced integrated feedback and proprietary high-speed gate drive error correction for ultra-low distortion and noise across the audio band. The device operates in AD-mode and can drive up to 2 x 175 W into 4 Ω load and 2 x 220 W into 3 Ω load.
