NOTES: (1) Sample tested—this parameter is guaranteed. (2) Offset voltage, offset current, and bias current are measured 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.
