D2-24044-MR-T

D2-24044-MR-T is a digital audio amplifier power stage. It is a high-performance, integrated Class-D amplifier power stage. The four power stage outputs are configurable as four separate Half-Bridge outputs, as two Full-Bridge outputs, or combinations of Half-Bridge and Full-Bridge. Individual power stage overload monitoring, on-chip temperature monitoring, and common alert logic outputs provide protection to integrate with the final system’s controller. The application includes PC/multimedia speakers, digital TV audio systems, portable device docking stations, and powered speaker systems.
