(1)

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

Statistical Quality Control (SQC) method.

(2)

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 specified on shipped

production material.

(3)

Offset voltage average drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change.

(4)

This parameter is specified by design and/or characterization and is not tested in production.

(5)

Positive current corresponds to current flowing into the device.

(6)

The short circuit test is a momentary open loop test.
