Limits over the operating temperature range are specified 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 specified on shipped production material. (3) Offset voltage average drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change. (4) Positive current corresponds to current flowing into the device. (5) This parameter is specified by design and/or characterization and is not tested in production. 6 Submit Documentation Feedback Copyright © 2008–2014, Texas Instruments Incorporated Product Folder Links: LMP7721 |
