TAS5132数据手册开发板套件编程器的评估板-音频放大器规格书PDF

描述 Description

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