Hi
I'm struggling to see if it's possible to use this device to measure low currents in the order of 10's of uA.
If I can use a 1k shunt resistor then I should be ok, but when doing so I get different measured results to that expected. For example, I have a 5V supply and a 200k load. The current should be 25uA but the INA226 reads 31uA.
My guess is that the INA226 is actually responsible for this difference due to the current into its sense pins. Am I right?
How else (what other device) can I measure low currents?
Thanks.
