GENERAL DESCRIPTION
The ADG721, ADG722, and ADG723 are monolithic CMOS
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 devices are packaged in both a tiny 3 mm × 2 mm
LFCSP and an MSOP, making them ideal for space-constrained
applications.
The ADG721, ADG722, and ADG723 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 the new generation of
DACs and ADCs from Analog Devices, Inc.
The ADG721, ADG722, and ADG723 contain two independent
single-pole/single-throw (SPST) switches. The ADG721 and
ADG722 differ only in that both switches are normally open
and normally closed, respectively. In the ADG723, Switch 1 is
normally open and Switch 2 is normally closed.
Each switch of the ADG721, ADG722, and ADG723 conducts
equally well in both directions when on. The ADG723 exhibits
break-before-make switching action.
