DESCRIPTION
The PA9605AP interface adaptor converts the SA9605APA (DIP-20) package to a
SA9105XP (DIP-40) footprint. This enables the evaluation of the SA9605APA using the
PM9105AP evaluation module.
It is advised that this Application Note should be read in conjunction with the PM9105AP
Application Note.

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.
