Current sampling circuit_2023-07-26_18-31-41

Overview

Use INA282 for current sensing, which can be filtered appropriately.
The sampling resistor should be as small as possible to ensure the sampling range.
Use INA282 for current sensing, which can be filtered appropriately.
Use a filter capacitor on the Vout pin to reduce noise.
