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

Table 11: DC and AC measurement conditions. Designers should check that the operating

conditions in their projects match the measurement conditions when using the quoted

parameters.
