DOUT is always active in serial mode (never tri-stated).
This simplifies the daisy chaining of the multiple devices.
DOUTcannotbe“wire-or”tootherSPIoutputs.Inaddition,
DOUT does not return to zero at the end of transmission,
i.e. when CS is pulled high.
A LTC6915 may be daisy-chained with other LTC6915s
or other devices having serial interfaces by connecting
the DOUT to the DIN of the next chip while CLK and CS
remain common to all chips in the daisy chain. The serial
data is clocked to all the chips then the CS signal is pulled
high to update all of them simultaneously. Figure 4
shows an example of two LTC6915s in a daisy chained SPI
configuration.
