Texas Instruments TAS5630B 300W Stereo Class D Amplifier

Texas Instruments TAS5630B 300W Stereo Class D Amplifier is a high-performance analog-input device with integrated closed-loop feedback PurePath HD technology. TAS5630B Class D Amplifier can drive up to 300W stereo into 4Ω to 8Ω speakers from a single 50V supply. PurePath HD technology enables traditional AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D amplifiers. Unlike traditional class-D amplifiers, the TAS5630B has a distortion curve that does not increase until the output levels move into clipping. This Texas Instruments stereo Class D amplifier is ideal for use in a variety of applications, including mini combo systems, AV receivers, DVD receivers, and active speakers.
