Hi Renato,
Apology for the late reply. Anyways, it is essential that the DOUT/RDY signal is monitored and a conversion is read only when RDY goes low. In continuous read mode, the data register is updated each time that a new conversion is available. Therefore, it is critical that a conversion is read completely before the next data register update. In continuous conversion mode, the data register is not updated if it is being read from. So, using continuous conversion mode is more flexible.
So, the process should be
- Monitor RDY on ADC1
- When RDY goes low, read conversion
- Select ADC2
- When RDY goes low, read conversion
- Select ADC3
- When RDY goes low, read conversion

Johnny
