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 characteristics Tables that follow, are de-
rived from tests performed under the Measure-
ment
Conditions
summarized
in
Table
13,
Operating and AC Measurement Conditions. De-
signers should check that the operating conditions
in their circuit match the measurement conditions
when relying on the quoted parameters.
Table 13. Operating and AC Measurement Conditions
Note: 1. To be characterized.
