GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG779 is a monolithic CMOS SPDT (single-pole,
double-throw) switch. This switch is designed on a submi-
cron 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 instru-
ments and with the new generation of DACs and ADCs from
Analog Devices.
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, 鈥? dB bandwidth
of greater than 200 MHz can be achieved.
The ADG779 is available in a 6-lead SC70 package.
1. Tiny 6-Lead SC70 Package.
2. 1.8 V to 5.5 V Single Supply Operation. The ADG779
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.
3. Very Low R

typ).
5. 鈥? dB Bandwidth >200 MHz.
6. Low Power Dissipation. CMOS construction ensures low
power dissipation.
7. 14 ns Switching Times.
