App note: High-speed level shifting using Si8XXX isolators


Silicon Lab’s Si86xx which provides digital isolation and voltage level shifting while Si823x as ISOdrivers, Link here (PDF)

Voltage level shifting is common in analog and mixed-signal system applications. While several technologies implement level shifting (e.g., HVIC processes, discrete circuits, dedicated level shifting ICs), recent advances in CMOS isolation technology enables fast, reliable, and highly-integrated ICs that are ideal for a broad range of level shifting applications. This application note discusses precision high-speed level shifting techniques using Silicon Labs’ Si8xxx Digital isolators and ISOdrivers. Specifically, this application note covers common-mode voltage level shifting, logic threshold voltage level shifting, and gate driver common-mode inversion.
