Specifications subject to change without notice.
Minimum and maximum specified limits on parameters that are guaranteed but not tested are six sigma values.
This bias is internally arranged to track the input voltage at INPT; it is not specified relative to ground.
Output Noise and Incremental Bandwidth are functions of Input Current; see Typical Performance Characteristics.
