EVALUATION BOARD CONFIGURATIONS

The ADP151 evaluation board is supplied with different
components, depending on the version ordered. Components
common to all versions are C1, C2, and J1. Figure 4 and
Figure 5 show the schematics of these evaluation board
configurations. Table 1 describes the components.
