Hello! It has been awhile since I have looked at electronics and circuit design. The problem at hand is akin to an audio application (ADC to DAC to sample and reproduce the signal) but I am interested in very low voltage signals and want to reach < 1 Hz frequencies.
There seem to be a plethora of good 24 - bit ADC/DAC combos at TI, but will the built in filtering suppress < 20 Hz?
I do see a good ADC in the instrumentation section (a bit slower than I want, http://www.ti.com/product/ads1278) but it doesn't seem to have a DAC counterpart.
