DESCRIPTION
The TAS5186A is a high-performance, six-channel,
digital-amplifier power stage with an improved
protection system. The TAS5186A is capable of
driving a 6-W, singleended
load up to 30 W per each
front/satellite channel and a 3-W, single-ended
subwoofer greater than 60 W at 10% THD+N
performance.
A low-cost, high-fidelity audio system can be built
using a TI chipset comprising a modulator (e.g.,
TAS5086) and the TAS5186A. This device does not
require power-up sequencing because of the internal
power-on reset.
The TAS5186A requires only simple passive
demodulation filters on its outputs to deliver
high-quality, high-efficiency audio amplification. The
device efficiency of the TAS5186A is greater than
90% when driving 6-W satellites and a 3-W subwoofer
speaker.
The TAS5186A has an innovative protection system
integrated on-chip, safeguarding the device against a
wide range of fault conditions that could damage the system. These safeguards are short-circuit protection,
overload protection, undervoltage protection, and
overtemperature protection. The TAS5186A has a
new proprietary current-limiting circuit that reduces
the possibility of device shutdown during high-level
music transients. A new programmable overcurrent
detector allows the use of lower-cost inductors in the
demodulation output filter.
