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.
1. Single/Dual Supply Operation. The ADG733 and ADG734 are
fully specified and guaranteed with 3 V and 5 V single supply
rails and ± 2.5 V dual supply rails.
Low power consumption and operating supply range of 1.8 V to
5.5 V and dual ± 2.5 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 channels
are switched OFF.
2. Low On Resistance (2.5 Ω typical)
3. Low Power Consumption (
