Hi,
I want to build a milliohm meter like this over here
The one that he is using is INA106.
It is expensive and also not available for me now. and I believe it is a DIFFERENTIAL AMPLIFIER not an instrumentation amplifier (which I am not sure is it better to use in that design or not!)
He mentioned somewhere in the comments that ina131 is replacement put also it is a little bit expensive for my application
I want to choose another one that can do the job and within a reasonable price
after some search, I have chosen INA333
I don't know if this is a good choose or not
Can someone help with this!!
What is the important parameter that I should look for
Is it the low offset voltage or low noise or low drift or is it low input BIAS current ??
I really don't know!!
