Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. (2) Typical Values represent the most likely parametric norm. (3) All limits are guaranteed by testing or statistical analysis. (4) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change. (5) Positive current corresponds to current flowing into the device. Copyright © 2000–2013, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LM8261 |
