5 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.
