Luca,
The TIDA-00302 document is good to reference for this application, be sure to take a look at the INA229 datasheet notes for filtering and dealing with transients as well:
Something to note is the maximum values for the series resistance (100Ω)…
Part Number: INA186 Other Parts Discussed in Thread: TIDA-00302 Hello,
TIDA-00302EVM has an external protection circuit to support IEC61000-4-5 and IEC61000-4-4 tests. The target of the document linked below is INA210-215, but is it also effective as a…
Hello,
Thanks for posting your questions.
1. The ADC is 12-bit so yes measurement resolution will meet 12-bit.
2. Maximum error is dependent upon the shunt resistor and the device gain you choose. So for example lets say you choose a 1-Ω shunt and set…
Transient robustness and ESD Ratings. If you are creating a new design, we recommend you use the INA199B or INA199C devices.
The B and C versions of the device have a different ESD cell than the A version. The C version has better gain error than the…
The trailing letters refer to device versions where transient robustness and ESD Ratings have changed.
If you are creating a new design, we recommend you use the INA21xB or INA21xC devices.
The B and C versions of the device have a different ESD cell…
Part Number: INA199 Other Parts Discussed in Thread: TIDA-00302 , INA168 I really would like to use a particular current shunt monitor in my system; however, the input voltage ratings are a little lower than what is required.Fortunately there is a little…
Peter,
Due to the holiday, our responses will be delayed. In the mean time, take a look at TIDA-00302 to see how to protect against transients in general for current shunt monitors. We'll review your questions more in the next couple days and get back…
Hey Richard,
There are other components you can use than TVS diodes such as ferrite beads and RC filters. For transient protection you can refer to one of our reference design here:

For sustained overstress conditions (e.g…
Hello Travis,
Thanks for choosing a TI product. I think this is a very reasonable failure mode and solution. Although I am not sure where you a placing the fuse and whether you are exceeding the absolute maximum common-mode (-0.3V to 26V) or maximum differential…
Ben,
The difference between Version A and Versions B and C are the internal ESD protection diodes and their structure. The internal component of the Version A device that will latch up during a high-voltage transient is not present in the B and C versions…
