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.

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)
