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 SOIC package.
