Overview
The ADG719BRM-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 can operate from a single-supply range of 1.8 V to 5.5 V, making it ideal for use in battery-powered instruments and with the new generation of DACs and ADCs from Analog Devices Inc.
The switch conducts equally well in both directions when on and exhibits break-before-make switching action, preventing momentary shorting when switching channels. It is available in a 6-lead SOT-23 package and an 8-lead MSOP package, making it suitable for space-constrained applications.
