The maximum time between conversions is 10,000 ns. If CNV± is left idle for a time greater than the maximum value of t
For the maximum CLK period, the window available to read data is t
frequency that can be used for a given conversion CNV frequency. In echoed-clock interface mode, n = 16; in self-clocked interface mode, n = 18.
