The is a third-generation high-performance integrated stereo Digital Amplifier Power Stage with an improved protection system. The TAS5142 is capable of driving a 4R bridge-tied load BTL at up to 100W per channel with low integrated noise at the output, low THD+N performance and low idle power dissipation. A high-fidelity audio system can be built using a chipset, comprising a modulator e.g., TAS5508 and the TAS5142. 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 12V for GVDD and VDD and at 32V for PVDD. The TAS5142 does not require power-up sequencing due to internal power-on reset. The efficiency of this digital amplifier is greater than 90% into 6R, which enables the use of smaller power supplies and heatsinks.
