NVE Introduces New GMR Current Sensor
AAV003-10E Has -80 to +80 Milliamp Range
EDEN PRAIRIE, Minn.January 7, 2009NVE Corporation
(Nasdaq: NVEC) today announced the introduction of the AAV003-10E Giant Magnetoresistive
(GMR) current sensor.
The
AAV003-10E combines an extremely low hysteresis GMR bridge sensor element with
an on-chip current strap. The bridge output voltage is bipolar and proportional
to the current through the strap over a -80 to +80 milliamp input range.
Typical sensitivity is a remarkable one millivolt per milliamp with a 12-volt
supply and no amplification, which is much higher than Hall effect sensors. Maximum
strap resistance is just 0.35 ohms for low loss and minimal circuit disruption.
Unlike shunt resistors, the output is independent of shunt resistance.
The parts come in an ultraminiature 2.5 millimeter by 2.5 millimeter six-pin TDFN
package.
AAV003-10E current sensors are targeted at circuit board current sensing for process
control and instrumentation. Their sensitivity makes them ideal for 4-20 milliamp
current loop detection.
Available now, AAV003-10E current sensors are priced at $1.66 each in 1,000-piece
quantities. Datasheets and more information are available at www.GMRsensors.com
or www.nve.com.
Giant Magnetoresistance (GMR) is a spintronic effect that produces a large change
in resistance of a conducting layer. “Giant” refers to its very large electrical
signal.
NVE is a leader in the practical commercialization of spintronics, a nanotechnology
that relies on electron spin rather than electron charge to acquire, store and
transmit information. The company manufactures high-performance spintronic products
including sensors and couplers that are used to acquire and transmit data. NVE
has also licensed its spintronic magnetoresistive random access memory technology,
commonly known as MRAM.
Statements used in this announcement that relate to future plans, events, or
performance are forward-looking statements that are subject to certain risks and
uncertainties including, among others the risk factors listed from time to time
in our filings with the SEC, including our Annual Report on Form 10-K and other
reports filed with the SEC.
