GENERAL DESCRIPTION

The ADG719-EP 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-EP 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, Inc.

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

directions when on. The ADG719-EP 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-EP is available in a 6-lead SOT-23 package.

Full details about this enhanced product are available in the

ADG719 data sheet, which should be consulted in conjunction

with this data sheet.
