I'm curious to hear if anyone has used this ADC with a DC-coupled input. If so, did you use a differential amplifier to drive it? Which part? Any passive implementation options?

Our LVDS EVMs often include a DC coupled option using our THS4541 fully differential amplifier. Although this part is not present on the ADC34xxEVM, this will work out just fine. Please see the attached schematic(s) of a couple EVMs which include this device. I am unaware of any passive DC coupled input options as the passive frontends are inherently AC coupled due to balun(s).
