1. The AAT2550 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured by design, characterization, and correla-

tion with statistical process controls.

2. End of Charge Voltage Accuracy is specified over the 0° to 70°C ambient temperature range.
