GENERAL DESCRIPTION
The ADG821, ADG822, and ADG823 are monolithic CMOS
SPST (single pole, single throw) 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, and 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, and
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, and ADG823 are available in an 8-lead
MSOP package.
