NOTES:
1. The maximum junction temperature of the LF398 is 150
°
C.
When operating at elevated ambient temperature, the packages must be derated
based on the thermal resistance specified.
2. Although the differential voltage may not exceed the limits given, the common-mode voltage on the logic pins must always be at least 2V
below the positive supply and 3V above the negative supply.
3. Derate above 25
