PA9605AP FUNCTIONAL DESCRIPTION 1. Interface Board The PA9605AP interface adaptor board (see Fig. 1) allows the connection of a SA9605APA (DIP-20) device to an evaluation board of type PM9105AP. This Interface Board inserts into the dual-in-line socket of the PM9105AP module in the same orientation that the SA9105XPA (DIP-40) device is normally inserted. Figure 1: Connection Diagram
