What Is A Digital Isolator?

In today's digital age, the electronic components industry is thriving, with digital isolators being a key focal point. This article delves into the definition, characteristics, advantages, and different types of digital isolators.

I. What are Digital Isolators?

Galvanic isolation is utilized to prevent DC and unwanted AC currents between two parts of a system while allowing signal and power transfer between them.

Digital isolators are integrated devices used to isolate digital signals and facilitate digital communication across an isolation barrier between microprocessors and data converters. Typically, they come into play after the ADC in a system, bridging microprocessors and FPGAs operating at different supply levels or interfacing communication boards sharing backplanes.
