Note 1. Derated above Ta = 25℃ in the Proportion of 5.6mW/℃
2. Absolute maximum ratings are stress ratings only and functional device operation is not implied. The device
could be damaged beyond Absolute maximum ratings.
3. The device is guaranteed to meet performance specifications within 0℃~70℃ operating temperature range
and assured by design from –20℃~85℃.
