(8) Output short circuit duration is infinite for VS < 6V at room temperature and below. For VS > 6V, allowable short circuit duration is 1.5ms. 5V Electrical Characteristics Unless otherwise specified, all limits guaranteed for at TJ = 25°C, V + = 5V, V− = 0V, V CM = VO = V +/2, and R f = 2kΩ, and RL = 1k Ω to V +/2.

(2) Typical values represent the most likely parametric norm. (3) Slew rate is the average of the rising and falling slew rates. (4) Guaranteed based on characterization only. (5) Positive current corresponds to current flowing into the device. (6) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change. 4 Submit Documentation Feedback Copyright © 2001–2013, Texas Instruments Incorporated Product Folder Links: LMH6645 LMH6646 LMH6647 |
