Hi
Now, we are considering following application using INA226Q1.
1. What do you think is this possible?
2. Can you check if our consideration is correct?
If "a" is Bus voltage gain error and "b" is Bus offset voltage, we think we can get the measured voltage Y1, Y2 as follows:
Y1 = aX1 + b
Y2 = aX2 + b
Y1 is measured voltage of X1.
Y2 is measured voltage of X2.
If measuring X1-X2, we would get Y1-Y2 = a(X1-X2).
So, we think the offset error would be canceled for upper measurement as long as in the fixed temperature and fixed Vs.
BestRegards
