High-speed output

The high-speed output function enables an output frequency of a maximum of 100 kHz with
an output current of a maximum of 100 mA. A high-speed output generates very steep
edges. The high-speed output generates signals at a higher frequency, but provides a lower
maximum load current.
The high-speed output is only available in two-channel operation and only without current
control.
The following table presents the minimum and maximum pulse duration, period duration and
frequency depending on whether or not the high-speed output is activated:
