NOTES: (1) Sample tested. (2) Offset voltage, offset current, and bias current are specified with the units fully warmed up. (3) Overload recovery is defined as
the time required for the output to return from saturation to linear operation following the removal of a 50% input overdrive. (4) 100°C/W for KU grade.
