Hi team,
I have some questions in below for the INA220.
1. For the INA220, the shunt voltage LSB is 10uV (in datasheet 7.5 DC acurracy).
So the current LSB* Rshunt should be bigger than 10uV?
2. In Configuration Register about ADC Settings (SADC [6:3]), not really understnd for this.
If SADC [6:3]= 0000, does that mean current_LSB should be changed to: max expected current/(2^9) ?
I don't know what's the difference for mode/sampling for 9-12 bit and 2-128 samples?
And not understand if I choose 9-bit mode, what's the impact?
Thank you!
