specification revision 0.98. Please refer to that speciation for further details.
Note 1: 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 guarantee performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: All voltages are measured with respect to GND, unless otherwise noted.
Note 3: When the input voltage (V
components and/or ESD protection circuitry are shown below for the LM41’s pins. The nominal breakdown voltage of the zener is 6.5 V. SNP stands for snap-back
device.
