Continuous Conversion Mode
Continuous conversion is the default power-up mode. The
AD7190 converts continuously, the RDY bit in the status
register going low each time a conversion is complete. If CS is
low, the DOUT/RDY line also goes low when a conversion is
completed. To read a conversion, the user writes to the com-
munications register, indicating that the next operation is a read
of the data register. When the data word has been read from the
data register, DOUT/RDY goes high. The user can read this
register additional times, if required. However, the user must
ensure that the data register is not being accessed at the
completion of the next conversion or else the new conversion
word is lost.
When several channels are enabled, the ADC continuously
loops through the enabled channels, performing one conversion
on each channel per loop. The data register is updated as soon
as each conversion is available. The DOUT/RDY pin pulses low
each time a conversion is available. The user can then read the
conversion while the ADC converts on the next enabled channel.
If the DAT_STA bit in the mode register is set to 1, the contents
of the status register are output along with the conversion each
time that the data read is performed. The status register indicates
the channel to which the conversion corresponds.
