4 Evaluation Board
4 Evaluation Board
In addition to the Test Board shown in Figure 3. intended also to evaluate the STA540SA
Amplifier, it is possible to order the dedicated STA543SA evaluation board of Figure 6.
The PCB layout (single layer) is shown in Figure 7.

4.1 Crcuit description
With this board it is possible to amplify three analog signals Left, Right, Subwoofer coming
from separated sources or to generate the BASS part to be sent to the Subwoofer via a
passive crossover network.
All the three channels have a Linear DC volume Control.
