Data Sheet
Figure 44 to Figure 49 show the digital filter frequency profiles for
the different oversampling ratios. The combination of the analog
antialiasing filter and the oversampling digital filter helps to reduce
the complexity of the design of the filter before the AD7607. The
digital filtering combines steep roll-off and linear phase response.
