TAS5768M - 20W Class-D Stereo PurePath™ Smart Amp with Ternary Modulation

The TAS576xM PurePath Smart Amp enhance the bass, sound fidelity and provide moreloudness 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. Theamplifier is thermally designed to fit with the typical speaker so it can handle high peaks for thetime it takes the speaker voice-coil to heat up, and then it lowers the average power to safelimits.

The wide supply range of 4.5 V to 26.4 V enables the use of a wide range of differentpower 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 thantheir average power rating, without fear of damage to the speaker through over excursion orthermal-overload.
