TAS3251 Audio Amplifier
Texas Instruments' 175 W stereo, 350 W mono, ultra-HD amplifier features advanced digital signal processing (DSP)
Texas Instruments' 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™ digital-to-analog converter (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's 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. This device operates in AD-mode and can drive up to 2 x 175 W into a 4 Ω load and 2 x 220 W into a 3 Ω load.
