Application notes:
An easy way to do Hall sensor measurements
The AST144P pin version can be used as pin-to-pin replacement for Siemens / Infineon KSY14 and KSY44 Hall sensors.
(RoHS and REACH compatible)
- Wide range from a milli-Tesla up to 10 Tesla and above
- Measures both positive and negative fields with high precision
- Very low noise
- Very wide temperature range; a high temperature version up to +250°C/+480°F is also available
- Low temperature coefficient
- Low temperature coefficient on offset
- Low drift as well as long term drift
- Ultra low PHE (Planar Hall Effect) Error.
- Z-field measurements show no X- and Y-field errors
- XRay resistant
For dynamic, low noise measurements, we recommend sensor currents of 1 mA or lower for each channel of the AST144. For higher output, sensor currents up to 5 mA can be used.
As a rule of thumb, the AST144 series gives an output of 0,2 V/T at 1 mA sensor current.
