Silicon Labs' Si824x audio drivers are isolated Class D gate drivers that power audio systems delivering from 30 W up to 1000 W of audio power. Based on Silicon Labs’ proprietary isolation technology, the Si824x Class D audio drivers incorporate input-to-output isolation, which enables level-translation of signals without additional external circuits. The Si824x audio drivers feature adjustable dead-time control for achieving optimal THD, overlap protection that safeguards against shoot-through current damage, robust immunity to latch-up and high-voltage transients, and lower BOM costs and PCB footprints compared to non-isolated gate drive solutions. See the sound quality performance of the Si824x audio driver over the audible spectrum using the Class D Sound Quality Demonstration.
