Notes:
3. This includes the on-chip digital filtering.
4. The maximum magnitude of the differential input voltage, Vdiff(in) is determined by the following:
Vdiff(in) < 300 mV - |Vcm/12.5 | and should never exceed 300mV.
Vcm is the common mode voltage which is applied to the instrumentation amplifier inputs.
The above equation should be used to calculate the allowable common mode voltage for a given
differential voltage applied to the first gain stage inputs. This limit ensures
that the instrumentation amplifier does not saturate.
5. Gain tracking accuracy can be significantly improved by uploading a calibrated gain word to the
gain register for each PGA gain selection.
6. The common mode voltage on the Voltage Reference Input, plus the reference range,
[(VREF+) - (VREF-)]/2, must not exceed ±3 volts.
