6-Channel, 210-W, Digital-Amplifier Power Stage
The TAS5186A requires only simple passive
demodulation filters on its outputs to deliver

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- Ω , singleended load up to 30 W per each
front/satellite channel and a 3- Ω , 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.
