Overview
The ADG759BCPZ-REEL, produced by Analog Devices Inc., is a low voltage, CMOS analog multiplexer designed for high-performance applications. This device comprises four differential channels and is capable of switching 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 ADG759 is ideal for battery-powered, portable instruments due to its low power consumption and operating supply range of 1.8 V to 5.5 V.
