I bought a pmod isns20 ... and have a question about the formula in this guide:https://digilent.com/reference/pmod/pmodisns20/reference-manual
I dont understand from where does the formula come from -> Ima = 1000/89,95 ..... i dont understand the 89,95 i have read multiple times the Datasheets ( ACC772,adc7476) .... my calculation would be as follows:
lsb = 3,3V ( operating voltage) / 4096 ( bit range frome the 12 bit adc)
x = read out bit word
mv = (x-2048) * lsb *1000
Ima = mv/66 ( sens from the sensor)
what is my mistake ? Can someone please help with the formula in the guide ?
