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) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using Statistical Quality Control (SQC) methods. (3) Typical numbers are the most likely parametric norm. (4) Slew Rate is the average of the rising and falling edges. (5) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change. (6) Negative input current implies current flowing out of the device. (7) The maximum output current (IOUT) is determined by device power dissipation limitations. 6 Submit Documentation Feedback Copyright © 2005–2013, Texas Instruments Incorporated Product Folder Links: LMH6551 |
