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 °C, at the following rates: F package at 6.2mW/ °C N package at 9.3mW/ °C D package at 8.3mW/ °C |
