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 vide quality ai.e., low ESR, equivalent series resistance, low inductance, low leakage, and constant capacitance over a frequency range from 20Hz to 6MHz a 0.1| capacitors presents no problem. Surface mount capacitors meeting these requirements are both inexpensive and plentiful.

The ML6428-1 also requires four 220F output couplin capacitors if all outputs are to be used. See Figure 1. However, some users may use values up to 1000 F tp pass specifications in the two-field test. In the  when wideband signals such as video needed coupling capacitors in the hundreds of F's, tantalums were to choice.
