INA2180-Q1: What are the differences between INA2181-Q1 and INA2180-Q1? With INA2181-Q1 to replace INA2180-Q1, is there any matters needing attention in the design?

Hi,

The difference between the two has to do with the fact that INA2181 output references are brought out to dedicated pins, while in INA2180 they are internally shorted to ground. Here is a side by side comparison(INA2180 and INA2181):

Electrical performance remains the same otherwise.

Hi,

We do offer a few dual channel current sense amplifiers. However after applying the requirement of being automotive grade and P2P, none appears to be able to replace INA2180-q1.

But you're welcome to take a look at these products, you can find the link here
