GENERAL DESCRIPTION
The ADG749 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 ADG749 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 ADG749 conducts equally well in both
directions when on. The ADG749 exhibits break-before-make
switching action.
Because of the advanced submicron process, 3 dB bandwidths
of greater than 200 MHz can be achieved.
The ADG749 is available in a 6-lead SC70 package.
PRODUCT HIGHLIGHTS
1.
1.8 V to 5.5 V Single-Supply Operation. The ADG749
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.
2.
Very Low RON (5 Ω Maximum at 5 V and 10 Ω Maximum
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 typical).
5.
3 dB Bandwidth > 200 MHz.
6.
Low Power Dissipation. CMOS construction ensures low
power dissipation.
7.
Fast tON/tOFF.
8.
Tiny, 6-lead SC70 Package.
