The TAS576xM PurePath Smart Amp enhance the bass, sound fidelity and provide more loudness and at the same time drive a speaker to its thermal and mechanical limits.

The TAS576xM contains two BTL class-D amplifiers – with up to 2x50W peak into 4Ω. The amplifier is thermally designed to fit with the typical speaker so it can handle high peaks for the time it takes the speaker voice-coil to heat up, and then it lowers the average power to safe limits.

The wide supply range of 4.5 V to 26.4 V enables the use of a wide range of different power supply options from 2-cell Li-Ion batteries to fixed 24 V supply.

TI’s PurePath Smart Amp technology allow speakers to be driven with more peak power than their average power rating, without fear of damage to the speaker through over excursion or thermal-overload.
