SA9605APA APPLICATION NOTE
PA9605AP
THREE PHASE POWER/ENERGY
METERING INTERFACE ADAPT OR
n Demonstration of the SA9605APA
device using a PM9105APE module
n Pulse rate selectable via jumper leads
n Energy direction indicator provided
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.
n Meets the accuracy requirements for
Class 1 AC Watt hour meters

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.
