DC AND AC PARAMETERS
This section summarizes the operating measure-
ment conditions, and the DC and AC characteris-
tics of the device. The parameters in the DC and
AC characteristics Tables that follow, are derived
from tests performed under the Measurement
Conditions summarized in Table
6
, Operating and
AC Measurement Conditions. Designers should
check that the operating conditions in their circuit
match the operating conditions when relying on
the quoted parameters.
