I noticed that the AD22151G sensor is magnetic - it's attracted to our magnet. What part of the sensor or package is magnetic/ferritic? How will this affect magnetic field measurements?
The leadframe of the AD22151 package contains 7000ppm of iron, so it will be slightly attracted to magnets. This has been observed to cause some hysteresis in very precise magnetic field measurements after being exposed to large magnetic fields, giving a rough error of about 0.1%.
I hope this helps!
