Overview
The ADG709CRU, produced by Analog Devices Inc., is a low voltage, CMOS analog multiplexer designed for high-performance applications. This device comprises four differential channels, allowing it to switch one of four differential inputs to a common differential output. The switching is controlled by 2-bit binary address lines A0 and A1, and an EN input is used to enable or disable the device. When disabled, all channels are switched off.
The ADG709CRU 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, which prevents momentary shorting when switching channels, ensuring reliable operation.
