NVE Introduces ADT-Series Three-Volt TMR Magnetic Switches
Expands NVE’s line of continuous-duty nanopower TMR switches

EDEN PRAIRIE, Minn.—November 14, 2019—NVE Corporation today announced an expansion of its line of continuous-duty nanopower Tunneling Magnetoresistance (TMR) magnetic switches with the new three-volt ADT-Series TMR switches. ADT sensors combine ultralow power and high speed, with no need for duty cycling.

Single-Cell Operation
ADT-Series sensors operate from 2.4 to 4.2 volts, making them ideal for lithium or lithium-ion batteries and 3.3-volt supplies. Previously-announced AHT-Series sensors operate from 0.9 to 1.8 volts for single-cell alkaline battery power.

Ultralow Power
TMR technology provides ultralow power, making these sensors ideal for battery applications such as utility meters, security systems, or portable instruments. Typical quiescent currents are just 0.6 microamps for the ADT-Series and 1 microamp for the AHT-Series, even with no duty cycling.

Configured as Switches
Outputs are configured as magnetic “switches,” turning on when a magnetic field is applied and off when the field is removed. The field can be either polarity, and magnetic operate points are extremely stable over supply voltage and temperature.

Speed and Wide Bandwidth
Continuous operation without duty cycling provides much higher speed than duty-cycled Hall effect sensors. AHT-Series sensors can switch at 3 kHz and ADT-Series up to a remarkable 20 kHz.

Magnetic operate points are as low as 1.5 mT (15 Oe).
AHT- and ADT-Series Sensors fit on the head of a pin

ADT and AHT sensors come in ultraminiature 1.1 by 1.1 by 0.35 millimeter ULLGA-4 packages.

Leaders in Practical Spintronics
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.
