1. Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Functional operation at conditions other than the operating conditions
specified is not implied. Only one Absolute Maximum Rating should be applied at any one time. The AAT1271 is guaranteed to meet performance specifications over the -40°C
to +85°C operating temperature range and is assured by design, characterization, and correlation with statistical process controls.
