ONO PurePath™ HD DIGITAL-INPUT POWER STAGE
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 8Speakers from a single 32.5V supply.
PurePath™ HD technology enables traditional AB-Amplifier performance (&
lt;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 clip
ping.
