NOTES: (1) FSR is Full Scale Range = 10V (0 to –10V). (2) Includes offset errors from all modes of operation. (3) Total noise is rms total of noise for the modes
of operation used. (4) CIN = capacitance of sensor connected to ACF2101 input; CINTERGRATION = integration capacitance = CINTERNAL + CEXTERNAL. (5) Errors created
when the internal switches are driven from one mode to another. (6) The charge transfer is 0.1pC; for an integration capacitance of 100pF, the resultant charge
offset voltage error is 1mV.
