VCP1000 Performance
Posted: Sat Jan 27, 2024 3:41 pm
The 20 bit ADC (VCP1000_0) states that is has a Measurement Error Max 0.01%. Does that mean the reported measurements can be off by as much as 0.0001 * 80V = 8mV even though it has 77μV resolution? Or is that error only at full scale?
More specifically, my application involves measuring differential voltages using multiple VCP1000's (6 of them). If I have one VCP1000 measuring a voltage of 18V and another measuring a voltage of 22V, for a differential voltage of 4V what would my max error be on the differential measurement?
Thank you for your help on this.
