Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified. (2) The Electrical Characteristics tables list specified specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not ensured. (3) Typical values represent most likely parametric norms at TA = +25ºC, and at the Recommended Operation Conditions at the time of product characterization and are not ensured. (4) Datasheet min/max specification limits are ensured by test or statistical analysis. (5) Enabling mono bit (MONO_ONLY in Output Control Register 01h) will save 400 μA (typ) form specified current. (6) Shutdown current is measured in a normal room environment. 6 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LM49321 LM49321RLEVAL |
