DESCRIPTION
The TAS5162 is a high performance, integrated
stereo digital amplifier power stage with an improved
protection system. The TAS5162 is capable of
driving a 6-Ω bridge-tied load (BTL) at up to 210 W
per channel at THD = 10%, low integrated noise at
the output, low THD+N performance without clipping,
and low idle power dissipation.
A low-cost, high-fidelity audio system can be built
using a TI chipset, comprising a modulator (e.g.,
TAS5508) and the TAS5162. This system only
requires a simple passive LC demodulation filter to
deliver
high-quality,
high-efficiency
audio
amplification with proven EMI compliance. This
device requires two power supplies, at 12 V for
GVDD and VDD, and at 50V for PVDD. The
TAS5162 does not require power-up sequencing due
to internal power-on reset. The efficiency of this
digital amplifier is greater than 90% into 6 Ω, which
enables the use of smaller power supplies and
heatsinks.
The TAS5162 has an innovative protection system
integrated on-chip, safeguarding the device against a
wide range of fault conditions that could damage the
system. These safeguards are short-circuit
protection, overcurrent protection, undervoltage
protection, and overtemperature protection. The
TAS5162 has a new proprietary current-limiting
circuit that reduces the possibility of device shutdown
during high-level music transients. A new
programmable overcurrent detector allows the use of
lower-cost inductors in the demodulation output filter.

The DDV package will deliver 300 W peak; however, this
is dependant on system configuration. The smaller pad
area also makes the thermal interface to the heatsink
more important. For multichannel systems that require
two channels to be driven at full power with the DDV
package option, it is recommended to design the system
so that the two channels are in two separate devices.

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.
GENERAL INFORMATION
Terminal Assignment
The TAS5162 is available in two thermally enhanced packages:
• 36-pin PSOP3 package (DKD)
• 44-pin HTSSOP PowerPad™ package (DDV)
Both package types contain a heat slug that is located on the top side of the device for convenient thermal
coupling to the heatsink.
