3 Description
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.
