Logic output. A logic low on this output indicates that a new output word is available from the AD7714 data
register. The DRDY pin will return high upon completion of a read operation of a full output word. If no data
read has taken place, after an output update, the DRDY line will return high for 500 ´ tCLKÊ IN cycles prior to
the next output update. This gives an indication of when a read operation should not be attempted to avoid
reading from the data register as it is being updated. DRDY is also used to indicate when the AD7714 has
completed its on-chip calibration sequence.
