I need to sense current from 1mA to 3A C.C. in non ol very few intrusive mode.
Are Hall sensors for my application?

Hi

Sensing current with Hall sensor is a good solution.

But you can also use others tecnologies like:
- Magnetoresistive Current Sensor.
- or Optic Current Sensor.

you can also use maxim's chips max471 or max472
you can use national's chip LM3812 and family

the intrusive resistance is only some milli-ohms

hope this helps.

Hello!

I'd like to tell you that in MAX471 and 472 you will have a lot of linearity problems in lower 10% of meassuring range.

Regards!
