The ML6428 comes in two versions, the -1 and the -2. All outputs must be AC coupled into their loads for the -1 version. The -2 version is DC coupled. Both versions require 0.1F capacitor input coupling. Finding video quality -- i.e., low ESR, equivalent series resistance, low inductance, low leakage, and constant capacitance over a frequency range from 20Hz to 6MHz -- 0.1F capacitors presents no problem. Surface mount capacitors meeting these requirements are both inexpensive and plentiful.
