Hello
I'm designing a current sensor using the DRV421that seems to work very well
My question is : if I have only to measure positive currents what is the best way to get a 0/5V signal (0V-->Imin=0Ampere 5-->Imax)?
Should I add and external fast operational amplifier in order to remove the 2.5V offset and get the correct amplification or can I directly work with the internal differential amplifier?
Even a range 0.5V/5V (0.5-->Imin=0Ampere 5V-->Imax) can be acceptable like other commercil sensor with ratiometric output
Thank you very much
Nicola
