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- 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 , 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.
