Where fs is the sampling frequency, and fc is the conversion frequency

fs = fc/5

when the device is in one channel/continuous conversion mode,

fs = fc/10

when the device is in one channel/continuous conversion mode,

fs = Conversion trigger strobe frequency when the device is in interrupt mode (RD or CSTART)
