Using the DR65-0109 to Drive SPDT PIN Switches
Introduction
For use as a replacement part to the DR65-0003
PIN Driver.
This Application Note describes how to use the
M/A-COM DR65-0109 Single Channel Driver for
FET Switches as a SP2T PIN Diode Driver. When
configured per the directions herein, the DR65-0109
will provide the same functionality as the DR65-0003
in the same package style, HOWEVER THE
PINOUT IS DIFFERENT. USING THE DR65-0109
AS A DIRECT DROP-IN REPLACEMENT
WITHOUT DOING A PCB CHANGE WILL NOT
