Q
What is the setting amplification factor time from 0 dB to 38 dB, if chip workwith 3.3 volt?
A
The PGA is implemented by changing the sampling of the input signal, this is acommon PGA structure for most of our sigma delta converters, therefore the
response time of the PGA is not an issue. Changing from 0 to 38db, is
equivalent to a step change or a channel change at the input. The delay to o/p
can be obtained by looking at the group delay of the filter for the various
sampling rates on page 2 of the datasheet.
