NVE is highlighted in a
recent article in Elektronik International titled, “Bye-Bye
Optocoupler.”
An excerpt: “Optocouplers are no longer fast enough for today’s data
technology. So what are the alternatives?” (spoiler alert: they’re made
by NVE). |

NVE will be closed Wednesday,

Our second family of
revolutionary Tunneling Magnetoresistance (TMR) magnetic switches are the three-volt
ADT-Series. They are nanopower, high speed, and ultraminiature.
Battery Operation
ADT-Series sensors operate from 2.4 to 4.2 volts, which is ideal for lithium or
lithium-ion batteries and 3.3-volt supplies.
Ultralow Power
TMR technology provides ultralow power. Typical quiescent supply current is just
0.6 µA, even with no duty cycling. That’s less than the self-discharge
rate of typical lithium-ion batteries, making the new sensors ideal for battery
applications such as utility meters or portable instruments.
High Speed
Continuous operation without duty cycling means the sensors are fast, and can
switch at more than 20 kHz.
Sensitive
Magnetic operate points are as low as 1.5 mT (15 Oe).
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 the magnetic operate point is extremely stable over supply voltage and temperature.
Ultraminiature
ADT sensors are in
a 1.1 mm x 1.1 mm x 0.35 mm (0.043 x
0.043 inch) ULLGA package.
Key Specifications
• 2.4 to 4.2 V operation for lithium or lithium-ion power
• 0.6 µA quiescent current
• 20 kHz switching speed
• Ultraminiature 1.1 x 1.1 mm x 0.35 mm package

Demonstration Board
The AG040T
Demonstration Board has an ADT923-14E sensor and an LED to show the
sensor output. It is is powered by a three-volt lithium coin cell (included).
The sensor’s low quiescent power allows the battery to last at least several
years with occasional LED use. A miniature bar magnet is included to activate
the sensor. The board is just 1.57 by 0.25 inches (40 x 6 mm).

A full-length article highlighting
NVE’s GMR and TMR isolators titled “Bye-Bye Optocouplers?” was
published in the October issue of Elektronik International. The article
was written by Wolf-Dieter Roth of NVE distributor Hy-Line.
An excerpt, “...GMR technology can also be used in magnetic sensors and data
couplers, such as the US company NVE under the brand name ‘IsoLoop.’”
