Overview
The ADG819BRM-REEL, produced by Analog Devices Inc., is a monolithic, CMOS, single-pole, double-throw (SPDT) switch. This device is designed on a submicron process, which provides low power dissipation while offering high switching speed, low on-resistance, and low leakage currents. The ADG819 is ideal for battery-powered and portable instruments due to its low power consumption and operating supply range of 1.8 V to 5.5 V. Each switch conducts equally well in both directions when on and exhibits break-before-make switching action, preventing momentary shorting when switching channels.
