All typical values are at TA = 25°C.
NOTES:
2. This is for a fixed channel in conversion mode 00 or 01. When switching the channels, additional multiplexer setting time is required
to overcome the memory effect of the charge redistribution DAC.
5. It is measured by applying a full-scale of 35 kHz signal to other channels and determining how much the signal is attenuated in the
channel of interest. The converter samples this examined channel continuously. The channel-to-channel isolation is degraded if the
converter samples different channels alternately.
