(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using the
statistical quality control (SQC) method.
(2) Typical values represent the parametric norm at the time of characterization.
(3) Offset voltage average drift is determined by dividing the change in V
OS
by temperature change.
(4) Positive current corresponds to current flowing into the device.
(5) This parameter is specified by design and/or characterization and is not tested in production.
(6) The short circuit test is a momentary test, the short circuit duration is 1.5 ms.
