(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. No guarantee of parametric performance is

indicated in the electrical tables under conditions different than those tested

(2)

Negative input current implies current flowing out of the device.

(3)

Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.

(4)

Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using

Statistical Quality Control (SQC) methods.

(5)

Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary

over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on

shipped production material.
