Hello,
I forward my question to you on the advice of:

I bought an evaluation board through mouser. When I connect the A3 evaluation module (power only and no current through the sensor), I already have an error / change of 22mV at the output just by holding it upside down. It doesn't matter where I do this. Office, workshop, etc.
With the A4 variant, this deviation is 40mV.
It looks like an offset is introduced by just turning it upside down.
shielding does not seem to have any effect.
What is going wrong here?
Regards,
