1. Specification is for parts in the -40 to +85 C range. Higher temperature ranges will result in increased
2. See
3. It is recommended to tie V
4. All functional no-supply pins are internally clamped to V
5. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
6. Power supply must maintain regulation within operating V
7. Current injection specification does not include ATD pins.
