(1) Refer to Driving Capacitive Loads section in Applications Information.
(2) With capacitive load, the slew rate can be limited by the short circuit current and the load error flag can trigger during slewing.
(3) 8μs plus number of chopping periods. See Applications Information, Internal Current Sources and Settling Time section.
