(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed 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 guaranteed on
shipped production material.
(3) Voltage average drift is determined by dividing the change in V
OS
by temperature change.
