NOTES: (1) Gains other than 1 and 100 can be set by adding an external resistor, RG between pins 2 and 15. Gain accuracy is a function of RG. (2) FS = Full Scale.

(3) Adjustable to zero. (4) VO = 0V, see Typical Curves for VCM vs VO. (5) VNOISE RTI = √V2N INPUT + (VN OUTPUT/Gain)2 + 4KTRG. See Typical Curves. (6) Time required

for output to return from saturation to linear operation following the removal of an input overdrive voltage.
