20-W/15-W STEREO DIGITAL AMPLIFIER POWER STAGE
A low-cost, high-fidelity audio system can be built
using a TI chipset, comprising a modulator (e.g.,
2
2×20 W at 10% THD+N Into 8- BTL at 18 V
TAS5086) and the TAS5102/TAS5103. This system
(With Heatsink for TAS5102)
only requires a simple passive LC demodulation filter
2×15 W at 10% THD+N Into 8- BTL at 15.5 V
to
deliver

amplification with proven EMI compliance. These
devices require two power supplies, at 3.3 V for
2×10 W at 10% THD+N Into 8- BTL at 13 V
VREG,
and
up
to
23
V
for
PVDD.

The TAS5102/TAS5103 are integrated stereo digital
amplifier power stages with an advanced protection
system. The TAS5102/TAS5103 are capable of
driving an 8-
bridge-tied load (BTL) at up to 20
W/15 W per channel with low integrated noise at the
output, low THD+N performance, and low idle power
dissipation.
