STEREO DIGITAL AMPLIFIER POWER STAGE
requires a simple passive LC demodulation filter to
deliver high-quality, high-efficiency audio amplification
2×100 W at 10% THD+N Into 4-
BTL (1)
with proven EMI compliance. This device requires two

power supplies, at 12 V for GVDD and VDD, and at
32 V for PVDD. The TAS5142 does not require

The TAS5142 has an innovative protection system
integrated on-chip, safeguarding the device against a
>100 dB SNR (A-Weighted)
wide range of fault conditions that could damage the
<0.1% THD+N at 1 W
system. These safeguards are short-circuit protection,

overcurrent protection, undervoltage protection, and
