10.3.3 Clock

The device uses an internal clock for conversion. Conversion duration may vary but is bounded by the minimum and maximum value of tconv, as specified in the Timing Requirements section. An external SCLK is only used for a serial data read operation. Data are read after a conversion completes and when the device is in acquisition phase for the next sample.
