Smart TMR Angle Sensor
The ASR002-10E is the world’ first Smart TMR Angle Sensor, combining a Tunneling Magnetoresistance (TMR) sensor element with elegant digital signal processing.

A high-speed SPI interface provides access to the sensor data, as well as user-programmable parameters:

Year in Review

new product highlights included:

AAT101 GMR Smart Magnetometer
The new SM124-10E Smart Magnetometer combines a versatile GMR sensor element with digital signal processing. Single-byte (eight-bit) digital data provides a slick, easy-to-use interface, and its unique architecture eliminates the need for any commands.

It features an I2C interface and a digital output with programmable thresholds. Unlike awkward, old-fashioned Hall-effect sensors, GMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. 
SM324-10E Smart TMR Magnetometer  
TMR Smart Magnetometer Sensor
The new SM324-10E combines an ultra-precise TMR sensor element with sophisticated three-byte (24-bit) digital signal processing.

Like the GMR version (above), this part has an I2C interface plus a digital output with programmable thresholds. And like GMR, TMR is sensitive in-plane for ease of use.
AAL024 Noncontact Current Sensor
The AAL024-10E combines small size, high sensitivity, and cross-axis sensitivity for an ideal current-over-trace sensor.
It provides 3.6 mV/V/Oe typical magnetic sensitivity over a 1.5 to 10.5 Oe linear range. It is inherently omnipolar for AC or DC measurements, and comes in an ultraminiature 2.5 mm x 2.5 mm x 0.8 mm TDFN6.
AAL024 Evaluation Board
Four AAL024 sensors (see above) in four different circuit board configurations. The 2" x 2" board provides isolated AC or DC measurement of currents up to 5 amps. Sensitivity is as high as to 60 mV/V/A typ, or 300 mV/A with a 5V supply.
40 Mbps QSOP
RS-485 Transceiver

The world’s fastest isolated RS-485 transceivers are now also the world’s smallest. The new IL3685-1E is an ultrahigh-speed isolated transceiver in NVE’s ultraminiature, low thermal resistance QSOP-16 package.
ADL-Series Sensors fit on the head of a pin Ridiculously Low Power Sensors
We’ve further tightened the already ridiculously low power consumption specifications of ADL-Series Nanopower Magnetic Switches. Power consumption is as low as 72 nW, so they will run nearly forever on a single lithium coin cell. ADL sensors are also NVE’s smallest parts at just 1.1 mm x 1.1 mm x 0.35 mm.
ADL021 Nanopower Sensor
Mini Eval Board

The AG040B is a 0.25 x 1.57 inch demo board with the ultralow-power, ultraminiature ADL021 magnetic switch (see above). Powered by a coin cell (included), the quiescent power is so low the battery will last indefinitely. An LED indicates when the sensor is activated; a miniature bar magnet is included.
Low-Power Isolators
With a typical total quiescent current of just 0.3 mA per channel, the new IL01x-Series low-power isolators draw one-fourth the power of our flagship products. The new isolators also feature 10 Mbps data rates, 2.5 kV isolation, and 44000-year barrier life.

MMM 2017  
NVE researchers authored a paper that will be presented at the Joint MMM-Intermag Conference, January 14 through January 18, 2019 in Washington, DC. The prestigious conference is only convened every three years.
