The TAS5612 is a high performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath HD) with the ability to drive up to 125W.(1) Stereo into 4 to 8 Ω Speakers from a single 32.5V 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 distortion curve only increases once the output levels move into clipping.
PurePath HD technology enables lower idle losses making the device even more efficient.
