DC and AC parameters
This section summarizes the operating measurement conditions, and the DC and AC
characteristics 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 25: 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.
