Smart
TMR Magnetometer |
|
|
The
new SM225-10E Smart Magnetometer provides a unique combination of speed
and precision. The smart sensor combines a Tunneling Magnetoresistance (TMR) sensor
element with sophisticated digital signal processing. A fast, reliable SPI interface
provides data as well as an external programming interface:
Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for
optimal current sensing and easy mechanical interfaces.
Key SM225-10E features and specifications include:
Wide 0 to 150 Oe / 0 to 15 mT linear range
Can detect magnets more than 50 mm away
Fast SPI interface
2% FS accuracy for 0 to 125°C
Fast 15 kSps update rate
Factory calibrated
Programmable offset and gain compensation
-40°C to 125°C operating range
Ultraminiature 2.5 x 2.5 mm TDFN package
A Family of Smart Magnetometers
The SM225 is the third member of NVEs groundbreaking smart magnetometer
line, joining the general-purpose SM124
and the ultra-accurate SM324.

Low
Supply Current
with the Worlds Only TMR Isolators |
|
|
A new demonstration
of the worlds only Tunneling Magnetoresistance isolators shows how little
current they use.
We power an IL012 isolator with a single lithium button cell, and show that the
quiescent current is less than 0.1 mA per channel:
IL01x Isolators are ideal for battery-powered instruments or 4-20 milliamp current
loops.
Various two- and four-channel configurations are available.
Key specifications include:
0.3 mA/channel typ. quiescent current
10 Mbps guaranteed data rate
No carriers or clocks for low EMI
44000 year barrier life
