1 Maximum deviation between +25°C readings after temperature cycling between –55°C and +150°C; guaranteed, not tested.

2 Conditions: constant 5 V, constant 125°C; guaranteed, not tested.

3 Leakage current doubles every 10°C.

Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min

and max specifications are guaranteed, although only those shown in boldface are tested on all production units.
