NEW! Nanopower TMR Magnetic Switches
We have expanded our industry-leading family of magnetic switches with high-sensitivity versions of our ADT9xx-Series Tunneling Magnetoresistance (TMR) sensors.

The new versions provide magnetic operate points as low as 1.5 mT. The field can be either polarity, and the magnetic operate point is extremely stable over supply voltage and temperature.

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 1 µA 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.

Configured as Switches
Outputs are configured as magnetic “switches,” turning on when a magnetic field is applied and off when the field is removed.

ADT sensors are in a 1.1 mm x 1.1 mm x 0.35 mm DFN4 package.

  ADT925-14E (NEW!) 1.5 mT
  ADT924-14E (NEW!) 2.2 mT
  ADT923-14E 3.2 mT
  ADT922-14E 4.5 mT

Demonstration Board

The AG040T Demonstration Board has an ADT923-14E sensor and an LED to show the sensor output. It 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).
