1. The AAT2820 is guaranteed to meet performance specifications from 0°C to 70°C. Specification over the -40°C to +85°C operating

temperature range is assured by design, characterization, and correlation with statistical process controls.

2. Loads greater than those listed in maximum output load conditions may cause permanent damage to the device.
