DESCRIPTION
The TAS5186 is a high-performance, six-channel,
digital-amplifier power stage with an improved protec-
tion system. The TAS5186 is capable of driving a
6-
, single-ended load up to 30 W per each
front/satellite
channel
and
subwoofer greater than 60 W at 10% THD+N per-
formance.

6-Channel, 210-W, Digital-Amplifier Power Stage
The TAS5186 requires only simple passive demodu-
lation filters on its outputs to deliver high-quality,
high-efficiency audio amplification. The efficiency of
the TAS5186 is greater than 90% when driving 6-
satellites and a 3-
subwoofer speaker.
The TAS5186 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 TAS5186 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 demodu-
lation output filter.

A low-cost, high-fidelity audio system can be built
using a TI chipset comprising a modulator (e.g.,
TAS5086) and the TAS5186. This device does not
require power-up sequencing because of the internal
power-on reset.
