SBAS459C – JANUARY 2010 – REVISED MARCH 2010
The maximum number of devices that can be daisy-chained depends on the data rate at which the device is
being operated. The maximum number of devices can be approximately calculated with Equation 7.
where:
NBITS = device resolution (depends on data rate), and
NCHANNELS = number of channels in the device (4, 6, or 8).
(7)
For example, when the ADS1298 (eight-channel, 24-bit version) is operated at a 2kSPS data rate with a 4MHz
fSCLK, 10 devices can be daisy-chained.
