EVALUATION BOARD HARDWARE
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.
