The
Worlds Most
Sensitive Magnetometer IC |
|
|
NVE has broken the
record for magnetometer sensitivity again with the new ALT021-10E Tunneling Magnetoresistance
(TMR) analog magnetometer. It has a remarkable sensitivity of 500 mV/V/mT.
It can precisely measure fields from less than a microtesla to 250 microtesla.

Bipolar Output
The differential bridge outputs are bipolar, meaning positive for a positive field
and negative for an opposite field polarity.
Specifications
• High sensitivity (500 mV/V/mT typical)
• Large signal (200 mV/V typical full-scale)
• Flexible 0 to 10 V supply (no minimum)
• 20 kiloohm device resistance for low power
• ±0.25 mT linear range
• High linearity (2% of full-scale)
• Ultra-low output temperature coefficient (±0.1%/°C)
