AD7788/AD7789
Continuous Read Mode
Rather than write to the communications register each time a
conversion is complete to access the data, the AD7788/AD7789
can be placed in continuous read mode. By writing 001111XX
to the communications register, the user needs only to apply the
appropriate number of SCLK cycles to the ADC and the data
word will automatically be placed on the DOUT/RDY line
when a conversion is complete.
Rev. 0 | Page 16 of 20
When DOUT/RDY goes low to indicate the end of a conver-
sion, sufficient SCLK cycles must be applied to the ADC and the
data conversion will be placed on the DOUT/RDY line. When
the conversion is read, DOUT/RDY will return high until the
next conversion is available. In this mode, the data can be read
only once. Also, the user must ensure that the data-word is read
before the next conversion is complete. If the user has not read
the conversion before the completion of the next conversion or
if insufficient serial clocks are applied to the AD7788/AD7789
to read the word, the serial output register is reset when the next
conversion is complete and the new conversion is placed in the
output serial register.
To exit the continuous read mode, the instruction 001110XX
must be written to the communications register while the RDY
pin is low. While in the continuous read mode, the ADC
monitors activity on the DIN line so that it can receive the
instruction to exit the continuous read mode. Additionally, a
reset will occur if 32 consecutive 1s are seen on DIN. Therefore,
DIN should be held low in continuous read mode until an
instruction is to be written to the device.
