AD5570
Readback
The AD5570 allows the data contained in the DAC register to
be read back, if required. As with daisy chaining, an external
pull-up resistor of ~5 kΩ on SDO is required. The data in the
DAC register is available on SDO on the falling edges of SCLK
when SYNC is low. On the 16
repeat SDIN with a delay of 16 clock cycles.
th
SCLK edge, SDO is updated to
68HC11*

To read back the contents of the DAC register without writing
to the part, take SYNC low while LDAC is held high.
Daisy-chaining readback is also possible through the SDO pin
of the last device in the DAC chain because the DAC data passes
through the DAC chain with the appropriate latency.
