... Inputs to the ADA4420-6 can be ac- or dc-coupled. For dc-coupled inputs, the signal must be completely contained within the input range 2.1 V. When using ac-coupled inputs, the lowest point of the signal is clamped to approximately 0 V. The ADA4420-6 outputs can be either ac- or dc-coupled. www.DataSheet4U.com When driving single ac-coupled loads in standard 75 Ω video distribution systems, a minimum capacitance of 220 μ ...
