GENERAL DESCRIPTION
The ADG1433 and ADG1434 are monolithic industrial-CMOS
(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 that
prevents momentary shorting when switching channels. An EN
input on the ADG1433 (LFCSP and TSSOP packages) and
ADG1434 (LFCSP package only) is used to enable or disable the
device. When disabled, all channels are switched off.
The iCMOS modular manufacturing process combines high
voltage, complementary metal-oxide semiconductor (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 performance, dramatically
lower power consumption, and reduced package size.
The ultralow on resistance and on resistance flatness of these
switches make them ideal solutions for data acquisition and gain
switching applications, where low distortion is critical. iCMOS
construction ensures ultralow power dissipation, making the parts
ideally suited for portable and battery-powered instruments.
