Standard applications circuits
Figure 7.
Figure 8.
The best audio performance is obtained with the configuration where each speaker has its
own DC blocking capacitor. If the application allows a little degradation of the spatial image it
is possible to connect a couple of speakers with only one low-value DC blocking capacitor.

A dedicated evaluation board is available for this application (see
