STEREO DIGITAL AMPLIFIER POWER STAGE
A low-cost, high-fidelity audio system can be built
using a TI chipset, comprising a modulator (e.g.,
2×20 W at 10% THD+N Into 8- BTL
TAS5086) and the TAS5132. This system only
2×25 W at 10% THD+N Into 6- BTL
requires a simple passive LC demodulation filter to
deliver
high-quality,
high-efficiency
audio
>100-dB SNR (A-Weighted)
amplification with proven EMI compliance. This
<0.1% THD+N at 1 W
device requires two power supplies, at 12 V for
Thermally Enhanced Package:
GVDD and VDD, and at 18 V for PVDD. The
–
DDV (44-pin HTSSOP)
TAS5132 does not require power-up sequencing due
to internal power-on reset. The efficiency of this
High-Efficiency Power Stage (>90%) With
digital amplifier is greater than 90% into 8
, which
140-m
Output MOSFETs
enables the use of smaller power supplies and
Power-On Reset for Protection on Power Up
heatsinks.
Without Any Power-Supply Sequencing
The TAS5132 has an innovative protection system
Integrated Self-Protection Circuits Including
integrated on chip, safeguarding the device against a
Undervoltage, Overtemperature, Overload,
wide range of fault conditions that could damage the
Short Circuit
system.
These
safeguards
are
short-circuit
PWM Activity Detector to detect stopped PWM
protection,
overcurrent
protection,
undervoltage
protection, and overtemperature protection. The
inputs and protect the system
TAS5132 has a new proprietary current-limiting
Error Reporting
circuit that reduces the possibility of device shutdown
EMI Compliant When Used With
during high-level music transients.

The TAS5132 is an integrated stereo digital amplifier
power stage with an advanced protection system.
The TAS5132 is capable of driving a 6-

output,
low

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
