Insulation Thickness in Reinforced Isolation Devices

Electrical systems often use insulation for proper operation of circuits, protection of operators from electric shock, or enhanced protection when voltages could generate lethal shocks. This video discusses how iCoupler digital isolator devices meet rigorous testing requirements to get approval for reinforced applications where insulation can be a matter of life or death.

USB Isolation Reference Circuits

These circuits are enabled by the industry's only single-chip USB digital isolator, the ADuM3160(2.5kV rms)/ADuM4160 (5kV rms). Based on ADI's iCoupler technology, the ADuM3160/ADuM4160 features:

  • D+/D- bidirectional isolation
  • USB 2.0 compliance
  • Reinforced isolation, up to 5 kV rms isolation rating.

Circuits from the Lab™ reference circuits are subsystem-level building blocks that have been engineered and tested for quick and easy system integration to help solve today's analog, mixed-signal, and RF design challenges.
