I want to use ADA4930 as an ADC driver in dc-coupled and single ended topology.
the gain is 0.5V/V and the source is 2Vpp and 50 Ohm. (Rf=301 Rg=294 Rt=56.9)
but the source has a little output offset. (some mV maximum)
I've studied in the Analog devices's application notes that I should apply some equal DC voltage at the inputs of the FDA.
I can not measure the output offset very accurate.
how should I provide this voltage and apply it at the second input of the FDA?!!!
please reply me as fast as you can. I don't have enough time.
