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 specific 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

IN

) at any pin exceeds the power supplies (V

IN

<

GND or V

IN

>

V+ ), the current at that pin should be limited to 5mA. The 20mA

maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5mA to four. Parasitic components
and/or ESD protection circuitry are shown below for the LM96000’s pins. The nominal breakdown voltage the zener is 6.5V. Care should be taken not to forward bias
the parasitic diode D1 present on pins D+ and D−. Doing so by more that 50 mV may corrupt temperature measurements. SNP stands for snap-back device.
