Overview
The ADG509FBRNZ is a CMOS analog multiplexer produced by Analog Devices Inc. This device is part of the ADG509F series, which features four differential channels. It is designed to switch one of four differential inputs to a common differential output, controlled by 2-bit binary address lines. The ADG509FBRNZ is notable for its fault protection capabilities, allowing it to withstand continuous voltage inputs from -40 V to +55 V, even when power supplies are turned off. This makes it highly reliable in various applications where signal integrity and protection are crucial.
