Response time
The response time (t
1
to t
3
) - that is the time from the application of the digital output values
in internal memory until the specified value is obtained at the analog output - is, in the most
unfavorable case, the sum of the cycle time and the settling time.
The worst case scenario is given, when the analog channel has been converted immediately
before a new output value is transferred, and is not converted again until all other channels
have been converted (cycle time.)
