5 DC and AC parameters
This section summarizes the operating measurement conditions, and the DC and AC
characteristics of the device. The parameters in Table 6: DC and AC characteristic, are
derived from tests performed under the measurement conditions summarized in Table 5:
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.
