AD7792/AD7793 Key Sheet Single Conversion Mode CS
In single conversion mode, the AD7792/AD7793 perform a single conversion and are placed in standby mode after the
DATA REQUEST
conversion is complete. DOUT/RDY goes low to indicate the
DIN
completion of a conversion. When the data-word has been read
DATA
from the data register, DOUT/RDY goes high. The data register
DOUT/RDY
can be read several times, if required, even when DOUT/RDY has gone high. 004
