Hi All,

I have two different current-shunt monitor IC to choose from below. I was thinking number 2 would be best to choose and more accurate, any ideas?

If cost or acceptance is not an issue which IC would be best to use and Why? Does LOWER input offset voltage is better?


1. INA213AIDCKR --> Max Input Offset Voltage(mV) = 0.1/5V

2. INA215AIDCKT--> Max Input Offset Voltage(mV) = 0.06/5V

Thanks
WJ
 
The input offset voltage is an error term. It means that with a zero input voltage you will have a non-zero output value.
So. If you don’t really care paying a little more, then a lower offset component is a better choice, as long as the other important parameters are also met.
 
They both have the same non linearity and G error specs -

The 215 has high G than 213
.
The offset and CMRR is -

The offset error difference between parts quite small as you can see.
