NVE is the subject of the cover story titled, “Giant Effect: GMR as a Replacement for Optocoupler Applications” in the January issue of ElektronikJournal, a leading German trade magazine.

The article covers the advantages of NVE’s GMR technology over conventional alternatives such as optocouplers and Hall-effect sensors.
For such a young technology, IsoLoop couplers are already in a very wide range of uses.

Love IsoLoops; Hate Optos

By Sandy “the Romantic” Templeton
Director, Isolator Product Development and Applications

Love IsoLoopsHate optos? You’re not alone

IsoLoop Isolators match optocoupler versatility but have smaller packages, less distortion, Evil Optosbetter reliability, and unlimited life.

IL600A-Series passive-input isolators are designed to be opto replacements with inputs similar to LEDs and outputs similar to phototransistors.

Inputs can be configured for inverting or non-inverting operation and accommodate a wide input voltage range. Versions are available with either CMOS or open-drain outputs.

Open-drain outputs can be wire-ORed together much like an optocoupler:

This illustrative circuit provides fail-safe output (logic high output for zero input current), 2.5 kVrms isolation, and 20 kV/µs transient immunity. Typical logic output sink current is 10 mA for each isolator.

So this Valentine’s Day, fall in love with IsoLoop Isolators—the opto alternativeSM.
