The TAS5611 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 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.
PurePath™ HD Enabled Integrated Feedback Provides:
Signal Bandwidth up to 80kHz for High Frequency Content From HD Sources
Ultralow 0.03% THD at 1W into 4
Flat THD at all Frequencies for Natural Sound
80dB PSRR (BTL, No Input Signal)
>100dB (A weighted) SNR
Click and Pop Free Startup
Pin compatible with TAS5630, TAS5615 and TAS5613
