1. The AAT1230/1230-1 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. Total input current with prescribed FB resistor network can be reduced with larger resistor values.
