Overview
The ADG719BRT-REEL7, produced by Analog Devices Inc., is a monolithic CMOS SPDT (Single-Pole Double-Throw) switch. This component is designed on a submicron process, which ensures low power dissipation while providing high switching speed, low on-resistance, and low leakage currents. The ADG719 operates from a single-supply range of 1.8 V to 5.5 V, making it suitable for battery-powered instruments and compatible with the latest DACs and ADCs from Analog Devices. It exhibits break-before-make switching action and conducts equally well in both directions when on. The device is available in a 6-lead SOT-23 package and an 8-lead MSOP package.
