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. |
