DESCRIPTION 6 Ω Satellite
The TAS5186 is high-performance, six-channel,
digital-amplifier power stage with an improved protec-
tion system. The TAS5186 is capable of driving
6-Ω, single-ended load up to per each
front/satellite channel and 3-Ω, single-ended
subwoofer greater than at 10% THD+N per-
formance. 3 Ω Subwoofer
low-cost, high-fidelity audio system can be built 0.01
using TI chipset comprising modulator (e.g.,
TAS5086) and the TAS5186. This device does not PO – Output Power – W
require power-up sequencing because of the internal
power-on reset.
