Limits apply for TA = 25°C.

(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 VDD = 3V state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not specified for parameters where no limit is given, however, the typical value is a good indication of device performance. (3) For DSBGA only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase ISD by a maximum of 2µA. (4) Typicals are measured at 25°C and represent the parametric norm. (5) Datasheet min/max specification limits are specified by design, test, or statistical analysis. (6) When driving 4 Ω loads from a 5V supply, the LM4898LD must be mounted to a circuit board with the exposed-DAP area soldered down to a 1sq. in plane of 1oz. copper. (7) Unterminated input. (8) 10 Ω terminated input. Copyright © 2004, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: LM4898 LM4898MMBD |
