Description

The ADG821 /ADG822/ADG823are monolithic CMOS single-pole, single-throw (SPST) switches. These switches are designed on an advanced submicron process that provides low power dissipation, yet gives high switching speed, low on resistance, and low leakage currents.The ADG821 / ADG822 / ADG823 are designed to operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments. Each switch of the ADG821 / ADG822 / ADG823 conducts equally well in both directions when on. The ADG821 / ADG822 / ADG823 contain two independent SPST switches. The ADG821 and ADG822 differ only in that both switches are normally open and normally closed, respectively. In the ADG823, Switch 1 is normally open and Switch 2 is normally closed. The ADG823 exhibits break-before-make switching action.The ADG821 / ADG822 / ADG823 are available in an 8-lead MSOP.APPLICATIONSPower routingBattery-powered systemsCommunication systemsData acquisition systemsAudio and video signal routingCellular phonesModemsPCMCIA cardsHard drivesRelay replacement
