Revolutionary new AHT-Series
Tunneling Magnetoresistance (TMR) magnetic switches are low-voltage, nanopower,
high speed, and ultraminiature.
Single-Cell Operation
AHT-Series sensors operate as low as 0.9 volts, so they can be powered by
single-cell alkaline batteries.
Ultralow Power
TMR technology provides ultralow power. Typical AHT-Series quiescent supply current
is just 1 µA, even with no duty cycling. That’s less than the self-discharge
rate of typical button cells, making the new sensors ideal for battery applications
such as utility meters or portable instruments.
Speed and Wide Bandwidth
Continuous operation without duty cycling means the sensors are fast, and can
switch at more than 1.5 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.

Smart Sensor Breakout Boards |
|
|
NVE expanded its Smart Sensor support ecosystem with breakout boards for all four
NVE
Smart Sensors. The boards include a Smart Sensor, six-pin header, and
a bypass capacitor, making it easy to evaluate the sensors and build prototypes:The
AG958-07E Breakout Board also has a connector to for use with the AG955-07E
Self-Contained SM124 Programmer or with customers’ own boards.
