AN614 A SIMPLE ALTERNATIVE TO ANALOG ISOLATION AMPLIFIERS

AN614 A SIMPLE ALTERNATIVE TO ANALOG ISOLATION AMPLIFIERS 1. Introduction Analog circuits sometimes require linear (analog) signal isolation for safety, signal level shifting, and/or ground loop elimination. Linear signal isolation is typically difficult to implement, costly, and often exhibits med.

Features

industry's limited device offerings often force the designer to make difficult trade-offs or add external circuitry for a complete solution. In addition, transformer-based ISOamps are susceptible to signal corruption from external field interference and errors due to poor common-mode transient immunity (CMTI). Optocoupler-based ISOamp versions also often suffer from poor linearity and even worse CMTI. This application note provides insight into a robust linear isolator reference design based on the Silicon Labs Si86xx family of CMOS digital isolators. Input Input  Amp Modulator or Driver I.
