Test levels (all values set by characterization and simulation): (A1) 100% tested at ≅ 25°C for all devices, overtemperature limits by characterization and simulation; (A2) 100% tested at ≅ 25°C for packaged devices, not tested in production for die sales (B) Not tested in production, limits set by characterization and simulation; (C) Typical value only for information;
Input offset voltage drift and input bias current drift are average values calculated by taking data at the end points, computing the difference, and dividing by the temperature range.
Current is considered positive out of the pin.
