Dear team,
I use INA213-Q1 to measure amount of current.
I want to increase the Rs (See the figure) value more than 10 ohm because of the noise problem, but you know, it's not recommended because of the sensing accuracy problem.
Speaking of my opinion, how about moving the filter location to the output of INA213-Q1 and increase RC value to reduce noise?
I know this will increase INA213-Q1 output impedance but they use OPA340NA to drive voltage to ADC input.
I believe OPA340NA solves INA213-Q1 high output impedance issue even if the filter is located in the back side. What do you think about this?
