NEW! NVE’s Most Sensitive
Sensor Ever
 
The new ALT023 is a version of the popular ALT025 Tunneling Magnetoresistance (TMR) analog magnetometer with ten times the sensitivity. The ALT023 can precisely measure fields from a few microtesla to 1 millitesla.
 
ALT02x Transfer Function
 
A unique
bipolar transfer function
Bipolar Output
The differential bridge outputs are bipolar, meaning positive for a positive field and negative for an opposite field polarity.
 
Specifications
   High sensitivity (200 mV/V typical full-scale)
   Flexible 0 to 5.5 V supply (no minimum)
   20 kiloohm device resistance for low power
   1 mT linear range
   High linearity (<1 % of full-scale)
   Ultra-low output temperature coefficient (0.1%/C)
ALT02x Equivalent Circuit
 
A differential bridge
analog output
   Up to 300 kHz bandwidth
   40 to 125 C operating range
   2.5 x 2.5 mm TDFN package

Applications
   Non-contact current sensing
   Motion, speed, and position control
   Mechatronics and robotics
   Geomagnetic navigation

Two Versions
There are currently two ALT-Series TMR Magnetometer versions:
