DC AND AC PARAMETERS

This section summarizes the operating and mea-

surement conditions, and the DC and AC charac-

teristics of the device. The parameters in the DC

and AC Characteristic tables that follow are de-

rived from tests performed under the Measure-

ment Conditions summarized in the relevant

tables. Designers should check that the operating

conditions in their circuit match the measurement

conditions when relying on the quoted parame-

ters.
