GENERAL DESCRIPTION

The ADG779 is a monolithic CMOS SPDT (single-pole,

double-throw) switch. This switch is designed on a submicron

process that provides low power dissipation yet gives high

switching speed, low on resistance, and low leakage currents.

The ADG779 operates from a single supply range of 1.8 V to

5.5 V, making it ideal for use in battery-powered instruments

and with the new generation of DACs and ADCs from Analog

Devices, Inc.

Each switch of the ADG779 conducts equally well in both

directions when on. The ADG779 exhibits break-before-make

switching action.

Because of the advanced submicron process, −3 dB bandwidth

of greater than 200 MHz can be achieved.

The ADG779 is available in a 6-lead SC70 package.
