Other Parts Discussed in Thread: THS4509, , OPA695, LMH6702, ADS5553, OPA659, THS4541, TINA-TI
I want to use LMH6552 or THS4509 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 some application notes and datasheets 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?!!!
