When single conversion mode is used on the AD779x, can CS be taken high after the single conversion is initiated ?

Question

ADIApproved · Accepted Answer

The serial interface is independent of the sampling process. So, once the single conversion is initiated, the AD779x will power up and perform the single conversion irrespective of the CS polarity. So, the user could take CS low, initiate the single conversion, and then take CS high again. When the conversion is complete, CS can be taken low to read the conversion and another single conversion can be started if required. When CS is taken high, the DOUT/RDY pin is tristated. Therefore, the DOUT/RDY pin will not indicate the end of the conversion. The user can determine the end of the conversion by reading the status register. Alternatively, the conversion time could be timed out by the microcontroller clock.)
