PRODUCTION DATA.
CS indicates an active-low, chip-select signal. CS is also used as a control signal to trigger a conversion on the falling edge. Each data frame begins with the falling edge of the CS signal. The analog input channel to be converted during a particular frame is selected in the previous frame. On the CS falling edge, the devices sample the input signal from the selected channel and a conversion is initiated using the internal clock. The device settings for the next data frame can be input during this conversion process. When the CS signal is high, the ADC is considered to be in an idle state.
