Are Hall sensors for my application? thx lollo

Apr 17, 2003 #2 G Guest Guest 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. try this links **broken link removed** **broken link removed** Best regards Pendragon

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!
