Output capacitor
The output can be either DC- or AC-coupled, and can be directly connected to the line via a
75-Ω resistor (4)
DC components in the load. Assuming a 150-Ω load, a coupling capacitor of 220 µF can be
used to provide a very low cut-off frequency close to 5 Hz

2. The 75-Ω resistor must be as close as possible to the output of the driver to minimize the effect of parasitic
capacitance.
S
is a 100 nF used to decrease the parasitic components of C in high frequencies.
