AD7606/AD7606-6/AD7606-4
Rev. C | Page 31 of 36
When the oversampling mode is selected for the AD7606/
AD7606-6/AD7606-4, it has the effect of adding a digital filter
function after the ADC. The different oversampling rates and
the CONVST sampling frequency produce different digital filter
frequency profiles.
Figure 56 to Figure 61 show the digital filter frequency profiles for
the different oversampling rates. The combination of the analog
antialiasing filter and the oversampling digital filter can be used
to eliminate and reduce the complexity of the design of any filter
before the AD7606/AD7606-6/AD7606-4. The digital filtering
combines steep roll-off and linear phase response.
