Description
IL500-Series isolators are low-cost isolators operating up to 2 Mbps over an
operating temperature range of
−40ºC
to 85ºC.
The devices use NVE’s patented* IsoLoop
®
spintronic Giant
Magnetoresistive (GMR) technology.
IL516
A unique ceramic/polymer composite barrier provides excellent isolation
and virtually unlimited barrier life.
IsoLoop is a registered trademark of NVE Corporation.
*U.S. Patent numbers 5,831,426; 6,300,617 and others.
