The MAX11600–MAX11605 feature input tracking cir-
cuitry with a 2MHz small signal bandwidth. The 2MHz
input bandwidth makes it possible to digitize high-
speed transient events and measure periodic signals
with bandwidths exceeding the ADC’s sampling rate by
using undersampling techniques. To avoid high-fre-
quency signals being aliased into the frequency band
of interest, anti-alias filtering is recommended.
