that swings above VREF voltage for positive-sense volt-
ages and below VREF for negative-sense voltages.
VOUT is equal to VREF when VSENSE is equal to zero.
Set the full-scale output range by selecting RSENSE and
the appropriate gain version of the MAX4080/
MAX4081.

Note: For Gain = 5 (F), RG1 = RG2 = 160k.
For Gain = 20 (T), RG1 = RG2 = 60k.
For Gain = 60 (S), RG1 = RG2 = 20k.
