TAS5611APHDR Class-D audio amplifier
The TAS5611APHDR is a dual-channel, 125W stereo/250W mono analog-input Class-D audio power amplifier engineered by Texas Instruments (TI) for high-fidelity sound reproduction. Built on TI's proprietary PurePath™ HD technology, it integrates closed-loop feedback to achieve ultra-low total harmonic distortion (THD) of 0.03% at 1W into 4Ω, matching traditional AB-class amplifier performance while delivering the power efficiency of Class-D designs. Designed for home theater systems, AV receivers, and active speakers, this device operates from a single 10.8V to 13.2V supply (up to 34.1V in select configurations) and supports a wide temperature range (0°C to 70°C). Its HTQFP-64 package ensures compact integration, while features like click-and-pop-free startup, self-protection circuits, and EMI compliance make it ideal for consumer and professional audio applications.
