DESCRIPTION

The TAS5132 is an integrated stereo digital amplifier

power stage with an advanced protection system.

The TAS5132 is capable of driving a 6-W bridge-tied

load (BTL) at up to 25 W per channel with low

integrated noise at the output, low THD+N

performance, and low idle power dissipation.

A low-cost, high-fidelity audio system can be built

using a TI chipset, comprising a modulator (e.g.,

TAS5086) and the TAS5132. 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 18 V for PVDD. The

TAS5132 does not require power-up sequencing due

to internal power-on reset. The efficiency of this

digital amplifier is greater than 90% into 8 W, which

enables the use of smaller power supplies and

heatsinks.

The TAS5132 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

TAS5132 has a new proprietary current-limiting

circuit that reduces the possibility of device shutdown

during high-level music transients.
