GENERAL DESCRIPTION
The ADG1233 and ADG1234 are monolithic iCMOS analog
switches comprising three independently selectable single-pole,
double throw SPDT switches and four independently selectable
SPDT switches, respectively.
All channels exhibit break-before-make switching action
preventing momentary shorting when switching channels.
An EN input on the ADG1233 and ADG1234 is used to
enable or disable the device. When disabled, all channels are
switched off.
The iCMOS (industrial-CMOS) modular manufacturing process
combines a high voltage complementary metal-oxide semi-
conductor (CMOS) and bipolar technologies. It enables the
development of a wide range of high performance analog ICs
capable of 33 V operation in a footprint that no other generation of
high voltage parts has been able to achieve. Unlike analog ICs
using conventional CMOS processes, iCMOS components can
tolerate high supply voltages while providing increased perfor-
mance, dramatically lowered power consumption, and reduced
package size.
The ultralow capacitance and charge injection of these multiplexers
make them ideal solutions for data acquisition and sample-and-
hold applications, where low glitch and fast settling are required.

Fast switching speed coupled with high signal bandwidth make the
parts suitable for video signal switching. iCMOS construction
ensures ultralow power dissipation, making the parts ideally
suited for portable and battery-powered instruments.
