GENERAL DESCRIPTION

The ADG719 is a monolithic CMOS SPDT 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 ADG719 can operate 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.

Each switch of the ADG719 conducts equally well in both di-

rections when on. The ADG719 exhibits break-before-make

switching action.

Because of the advanced submicron process, –3 dB bandwidths

of greater than 200 MHz can be achieved.

The ADG719 is available in a 6-lead SOT-23 package and an

8-lead

µSOIC package.

PRODUCT HIGHLIGHTS

1. +1.8 V to +5.5 V Single Supply Operation. The ADG719

offers high performance, including low on resistance and fast

switching times and is fully specified and guaranteed with

+3 V and +5 V supply rails.

4. –3 dB Bandwidth >200 MHz.

5. Low Power Dissipation. CMOS construction ensures low

power dissipation.

7. Tiny 6-lead SOT-23 and 8-lead

µSOIC packages.
