We have expanded our
industry-leading family of magnetic switches with high-sensitivity versions of
our ADT9xx-Series Tunneling Magnetoresistance (TMR) sensors.
Sensitive
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.
Ultraminiature
ADT sensors are in a 1.1 mm x 1.1 mm x 0.35 mm DFN4 package.
In Stock
Four ADT9xx-Series parts are now available:
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).
