Overview
The ADG5209BRUZ, manufactured by Analog Devices Inc., is a high-performance analog switch designed for applications requiring a 4:1 multiplexer/demultiplexer configuration. This device is part of the ADG5208/ADG5209 family, which features monolithic CMOS analog multiplexers. The ADG5209 specifically switches one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. It also includes an enable (EN) input to control the device's operation. The ADG5209 is notable for its ultralow capacitance, low charge injection, and fast switching speed, making it ideal for data acquisition, sample-and-hold applications, and video signal switching.
