1 Minimum and maximum specified limits on parameters that are guaranteed but not tested are six sigma values.

2 Other values of logarithmic intercept can be achieved by adjusting RREF.

3 Output noise and incremental bandwidth are functions of input current measured using the output buffer connected for GAIN = 1.
