Overview
The ADG1609BCPZ-REEL7, produced by Analog Devices Inc., is a monolithic 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). It features an enable input (EN) that allows the device to be enabled or disabled, with all channels switching off when disabled. The ADG1609 is particularly suited for applications requiring low on-resistance, low distortion, and ultralow power dissipation, making it ideal for data acquisition and gain switching in various electronic systems.
