- [FAQ] What are the benefits of Opto-emulators vs. Optocouplers?
- Allows isolated feedback for power-supply regulation
- Performance upgrade from traditional optocouplers
- Allows tight current transfer ratio (CTR) performance and no light-emitting diode (LED) aging. Uses TI's Silicon Dioxide isolation technology.
- Protects low-voltage parts in a system from high-voltage circuits
