The SampleSet approach provides greater sequencing
flexibility for multichannel applications while alleviat-
ing significant microcontroller communication overhead.
SampleSet technology allows the user to exploit available
ADC input bandwidth without need for constant commu-
nication between the ADC and controlling unit. The user
may define and load a unique sequencing pattern into
Figure 9. SampleSet Use-Model Example

the ADC allowing both high- and low-frequency inputs
to be converted appropriately without interface activity.
With the unique sequence loaded into ADC memory, the
pattern may be repeated indefinitely or changed at any
time.
For example, the maximum throughput of MAX11335–
MAX11340 is 500ksps. Traditional ADC scan modes
