GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
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.
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.
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, Inc.
2. Very Low RON (4 Ω Max at 5 V and 10 Ω Max at 3 V). At 1.8 V
operation, RON is typically 40 Ω over the temperature range.
3. Automotive Temperature Range: −40°C to +125°C.
4. On Resistance Flatness (RFLAT(ON)) (0.75 Ω typ).
5. −3 dB Bandwidth > 200 MHz.
Each switch of the ADG719 conducts equally well in both
directions when on. The ADG719 exhibits break-before-make
switching action.
6. Low Power Dissipation. CMOS construction ensures low
power dissipation.
Because of the advanced submicron process, −3 dB bandwidths
of greater than 200 MHz can be achieved.
7. Fast tON/tOFF
.
8. Tiny, 6-lead SOT-23 and 8-lead MSOP packages.
The ADG719 is available in a 6-lead SOT-23 package and an
8-lead MSOP package.
