On page 12 the data sheet of the DDC316 states:
Table 1:
Range3 -> Input Range = –0.1876pC to 12pC
Table 2:
–1.7857% FS = 0x0000 with –1.7857% * 12pC = -0.214284pC
How should I understand the difference of the two numbers –0.1876pC != -0.214284pC for the same input value?
Is there a hidden recommendation to always calibrate the DDC316 channels to get a precise current measurement?
