Single Conversion and Reading Data
When the Mode register is being written, the ADC Status Byte
is cleared and the
RDY pin goes high regardless of its previous
state. When the single conversion command is written to the
Mode register, the ADC starts the conversion on the channel
selected by the address of the Mode register. After the conversion
is completed, the Data register is updated, the Mode register is
changed to Idle mode, the relevant RDY bit is set, and the
RDY
pin goes low. The RDY bit is reset and the
RDY pin returns
high when the relevant Channel Data register is being read.
Figure 7 shows the digital interface signals executing a single
conversion on Channel 0, waiting for the
RDY pin low, and
reading the Channel 0 Data register.
Dump Mode
When the DUMP bit in the Mode register is set to 1, the Chan-
nel Status register will be read immediately by a read of the
Channel Data register regardless of whether the Status or the
Data register has been addressed through the Communication
register. The DIN pin should not be high while reading 24-bit
data in Dump mode. Otherwise the AD7738 will be reset.
Figure 8 shows the digital interface signals executing a single
conversion on Channel 0, waiting for for the
RDY pin low, and
reading the Channel 0 Status register and Data register in the
Dump mode.
