Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. (2) All limits are specified by testing, design, or statistical analysis. (3) Typical values represent the most likely parametric norm 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. (4) Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change. (5) This parameter is specified by design and/or characterization and is not tested in production. (6) Positive Bias Current corresponds to current flowing into the device. (7) The number specified is the average of rising and falling slew rates and measured at 90% to 10%. 6 Submit Documentation Feedback Copyright © 2009–2015, Texas Instruments Incorporated Product Folder Links: LMP8645 LMP8645HV |
