Because they rely
on electron spin, NVE sensors and isolators are inherently much less susceptible
to ionizing radiation than conventional charge-based devices.
have tested NVE basic elements at up to 1.1 terarad per second without failure.
That would be a fatal X-ray dose in less than a nanosecond.
Year in Review|
wish our readers a successful and prosperous 2011. It was a good year for NVE with many new customers, new products, added distributors, and prestigious awards:|

If you have a New Years resolution
to get more more resolution for your gear-tooth encoders (and who doesnt),
we have the solution.
NVE GT Sensors use high-sensitivity, low-hysteresis
GMR to detect even the smallest gear teeth. That means you can use finer-tooth
encoder gears for more angular resolution and better accuracy.
are designed for detection of ferrous gear teeth and magnetic encoder wheels in
industrial speed sensing. The sensor produces a sinusoidal output with one cycle
per tooth with wide air-gap and temperature tolerances.
Click on our new
video for practical tips on using GT Sensors:
are available with analog or digital outputs. Dual-output versions are available
with the second output phase shifted with respect to the first for quadrature
to determine direction.
Low profile MSOP8, TDFN SO8, and TDFN6 packages
allow GT Sensors to fit in the tightest spaces. An evaluation kit is available
with a variety of sensors, magnets, and PCBs.
So resolve to be more precise
this year with GT Sensors. Order an evaluation
kit and try them yourself:

Real-world questions from the NVE Application Desk|
By Sandy Templeton
Director, Isolator Product Development and Applications
Q. I have a circuit where the supply voltage may dip below the 3 V spec. (as low as 2.8 V under some circumstances). Is there anything I can do to increase the chances the isolator will continue to work?
A. While we can't guarantee the parts will work below the 3 V spec., IsoLoop isolators are remarkably forgiving. Some suggestions to maximize supply voltage design margin:
| || ||Place ceramic decoupling capacitors as close to the power and ground pins as possible to limit losses due to stray inductance. In this case we'd recommend two decoupling capacitors100 pF in parallel with 100 nF. The smaller capacitor will have lower ESR and inductive losses; the larger provides most of the switching energy. The smaller capacitor should be the one closer to the pins.|
| || ||Increase the data rate (1 Mbps or higher if possible). Because of their unique design, IsoLoop Isolators actually work better at higher speed. Similarly, do not limit slew rate of the input signals.|
