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.
