Hi

Can anyone help me with this?
If a Hall effect magnetic sensor is designed to operate at 30°C, how much temperature variation would be tolerable for a Hall voltage accuracy of ±10% -I have I graph of hall voltage vs the absolute temperature but I am not sure how to go about this

Well, find compare the graphed output voltage at 30 deg too the temperature you expect to operate it at and see if it varies by more than 10%

Hi Steve

Thanks for the reply. I'm kinda confused because i dont know the temperature its supposed to operate at .
I have attached the graph

Tip.....it is in reference to it's environment. I'm guessing it would be of little concern to you.

The graph showing 300 Kelvin is equal to 80 degrees F (27C) it goes to 440K (332F / 167C)

Since this is mostly above normal environmental conditions, one might assume it is intended to show how the device should be derated under extreme conditions.

Since the curve seems to be flattening out below 320K (116F / 47C), one might assume that the device performance is more linear at lower temperatures.
