Demonstration boards and applications suggestions

In addition to the test and applications board shown in Figure 3 on page 8, two

demonstration boards are also available:

STA540SA-2.1CH Eval-Board

STA540SA-BTL Eval-Board

These two evaluation boards are briefly described in the following section.

Note:

The test and application board shown in Figure 3 on page 8 is common to the STA543

amplifier and is intended to verify all the possible application configurations offered by the

STA540SA.
