Overview
The ADG709BRU-REEL, produced by Analog Devices Inc., is a low voltage, CMOS analog multiplexer. This device is designed to switch one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. An additional EN input allows for enabling or disabling the device, with all channels switching off when disabled. The ADG709 is particularly suited for battery-powered, portable instruments due to its low power consumption and operating supply range of 1.8 V to 5.5 V. It features break-before-make switching action, preventing momentary shorting during channel switching.
