TAS5142 is a stereo digital amplifier with an output power of up to 2×100 watts. It works at a voltage of 12V and 32V. The chip has multiple protection circuits to protect the system from damage.
The TAS5142 is a third-generation, high-performance, integrated stereo digital amplifier power stage designed for high-quality, high-efficiency audio amplification. It is capable of driving a 4-bridge-tied load (BTL) at up to 100 W per channel with low integrated noise at the output, low THD+N performance, and low idle power dissipation. The device is part of a low-cost, high-fidelity audio system that can be built using a TI chipset, comprising a modulator and the TAS5142, requiring only a simple passive LC demodulation filter.

The TAS5142 is available in a 36-pin PSOP3 package (DKD) and a 44-pin HTSSOP PowerPad package (DDV).
No, the device does not require power-up sequencing due to an internal power-on reset.
The device requires two power supplies: 12 V for GVDD and VDD, and 32 V for PVDD.
