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

minimum and maximum specifications are guaranteed,although only those shown in boldfaceare tested on all production units.

2

The LFCSP package has a reduced operating temperature range of −40°Cto +125°C.

3

Maximum deviation between +25°Creadings after temperature cycling between −55°Cand +150°C; guaranteed, not tested.

4

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

5

Leakage current doubles every 10°C.
