DC and ac parameters

DC and ac parameters

This section summarizes the operating and measurement conditions, as well as the dc and

ac characteristics of the device. The parameters in the following dc and ac characteristic

tables are derived from tests performed under the measurement conditions listed in the

relevant tables. Designers should check that the operating conditions in their projects match

the measurement conditions when using the quoted parameters.
