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
at that pin should be limited to 10 mA. The 100 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies
with an input current of 10 mA to ten. Parasitic components and/or ESD protection circuitry are shown below for the LM96194’s pins. Care should be taken not
to forward bias the parasitic diode, D1, present on pins D+ and D− as shown in circuits C and D. Doing so by more than 50 mV may corrupt temperature
measurements. D1 and the ESD Clamp are connected between V+ (V
