4. The maximum magnitude of the differential input voltage, Vdiff(in) is determined by the following:
5. Gain tracking accuracy can be significantly improved by uploading a calibrated gain word to the
6. The common mode voltage on the Voltage Reference Input, plus the reference range,
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.
gain register for each PGA gain selection.
[(VREF+) - (VREF-)]/2, must not exceed 3 volts.
