Can the AD22151G be used in a compass application?
The strength of Earth’s magnetic field ranges from 0.25 G to 0.65 G. The AD22151 has a sensitivity of 0.4mV/G. If you want 0.65 G to map to full scale, then a sensitivity of 2.5V per 0…
In datasheet AD22151G Package Power Dissipation is 25mW.
VCC Operating 5.0V typ. and ICC Operating 6.0mA typ..
I think that it is difficult to use because there is no room.
Or is it no problem to use it with 25 mW or more?
Can you recommend for me some linear hall effect sensors? I need to measure magnetic field in range between 10mT and 0.5T with a good sensivity.
AD22151G is the only Hall effect device we currently have released : http://www.analog.com/en/other…
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?
I'm sorry EngineerZone doesn't currently provide a support community for this particular Analog Devices product.
To get support on this product, I would suggest submitting your question to the Analog Devices support team in your region…
I made a magnetic field module using the AD22151 sensor based on the bipolar configuration in the datasheet. The sensitivity S is determined by R3 and R2. Theoretically speaking, my sensor module should be able to measure -8000 to +8000 Gauss.
