(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using the
Statistical Quality Control (SQC) method.
(2) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(3) Offset voltage average drift is determined by dividing the change in V
OS
at the temperature extremes by the total temperature change.
(4) This parameter is specified by design and/or characterization and is not tested in production.
(5) Positive current corresponds to current flowing into the device.
