Overview
The ADG719BRTZ-500RL7, produced by Analog Devices Inc., is a monolithic CMOS SPDT (Single-Pole Double-Throw) switch. This device 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 use in battery-powered instruments, as well as with the latest DACs and ADCs from Analog Devices.
The switch conducts equally well in both directions when on and exhibits break-before-make switching action. It is available in both 6-lead SOT-23 and 8-lead MSOP packages, offering flexibility in design and application.
