Hello,
I have to realize a high side current measurement with the following parameters:
Current to be measured: 0 ... 30mA
Accuracy: 0.1mA
Offset Voltage: 24V
I have found the INA226. This seems to be an interesting IC to solve the problem. Using a 2 Ohm shunt resistor would result in a maximum current of ca. 40mA. Is therefore a precission shunt resistor necessary or may the resistance value be compensated by calibration? Is the INA226 a good choice for this application or is there an IC that is better suited?
Best regards
Markus
