Minimum and maximum specified limits on parameters are guaranteed but not tested and are six sigma values.
2
This bias is internally arranged to track the input voltage at INPT; it is not specified relative to ground.
3
Output noise and incremental bandwidth are functions of input current; see the Typical Performance Characteristics section.
