Description

The TAS3251 Ultra-HD audio evaluation module demonstrates the TAS3251 integrated circuit from 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™ DAC with integrated DSP for advanced audio processing, including SmartAmp and SmartEQ. The integration of this 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 220W into 3-Ω load.

The TAS3251EVM features support for multiple audio input formats including USB, Optical SPDIF, Coax SPDIF and direct I2S. This EVM can be configured as a stereo (2 x BTL), mono (1 x PBTL) or active crossover two way amplifier. Get started quickly by using the preprogrammed process flows included in the onboard MSP430, or use PurePath(TM) Consle 3 for full control and tuning. Configure equalization (EQ), dynamic range control (DRC), automiatc gain limiter (AGL), as well as advanced speaker protection with SmartAmp.
