Overview
The ADG722BRMZ-REEL7, produced by Analog Devices Inc., is a monolithic CMOS single-pole/single-throw (SPST) switch. This device is part of the ADG721, ADG722, and ADG723 series, which are designed to operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments and with modern DACs and ADCs. The ADG722 features two independent SPST switches, both of which are normally closed. Each switch conducts equally well in both directions when on, and the device exhibits low power dissipation, high switching speed, low on resistance, and low leakage currents.
