Hello
We are having issues with the suggested calibration equations, datasheet page 12:
- Can you please confirm full scale Vshunt range if PGA=/1. Page 5 suggests it is 40mW, but given the 10mV LSBit and 12bit output, shouldn't it be 40.96mV?
- Equation 2 is using a 2^15 divider, even though this is a 12b ADC part. Why not just use V_lsbit (10uV) / Rshunt to get the current_LSB?
- What is the 'Maximum Expected Current' in equation 2 supposed to be? Is it 40mV/Rshunt? Or the end application's full range target, even if it doesn't use up the whole 40mV range?
- Equation 1 seems to be calculating the number of steps that fit in the ADC's 40.96mV full range, is this correct?
Thank you,
Ryan B.
