(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional but do not ensure specific performance limits.Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensures specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given; however, the typical value is a good indication of device performance. (3) Datasheet min/max specification limits are specified by design, test, or statistical analysis. (4) Typicals are measured at 25°C and represent the parametric norm. (5) Limits are specified to TI's AOQL (Average Outgoing Quality Level). (6) The NGY0010A package has its exposed-DAP soldered to an exposed 1.2in2 area of 1oz. Printed circuit board copper. (7) The limit is specified over the temperature range of –40°C to +85°C. (8) 10 Ω terminated input. 4 Submit Documentation Feedback Copyright © 2004–2011, Texas Instruments Incorporated Product Folder Links: LM4911 LM4911Q |
