DC and AC characteristics

This section summarizes the DC and AC characteristics of the device. The parameters in

the DC and AC characteristics table that follows are derived from tests performed under the

test conditions (see Table6 on page10). Designers should check that the operating

conditions in their circuit match the operating conditions when relying on the quoted

parameters.
