GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG733 and ADG734 are low voltage, CMOS devices
comprising three independently selectable SPDT (single pole,
double throw) switches and four independently selectable SPDT
switches respectively.
Low power consumption and operating supply range of 1.8 V to
5.5 V and dual
鹵
3 V make the ADG733 and ADG734 ideal for
battery powered, portable instruments. All channels exhibit
break-before-make switching action preventing momentary
shorting when switching channels. An
EN
input on the ADG733
is used to enable or disable the device. When disabled, all chan-
nels are switched OFF.
These 2鈥? multiplexers/SPDT switches are designed on an
enhanced submicron process that provides low power dissipation
yet gives high switching speed, very low on resistance, high signal
bandwidths and low leakage currents. On resistance is in the region
of a few ohms, is closely matched between switches and very flat
over the full signal range. These parts can operate equally well
in either direction and have an input signal range which extends
to the supplies.
The ADG733 is available in small TSSOP and QSOP packages,
while the ADG734 is available in a small TSSOP package.
1. Single/Dual Supply Operation. The ADG733 and ADG734 are
fully specified and guaranteed with 3 V and 5 V single supply
rails and
鹵
3 V dual supply rails.
2. Low On Resistance (2.5
鈩?/div>
typical).
3. Low Power Consumption (<0.01
碌W).
4. Guaranteed Break-Before-Make Switching Action.
