All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input on the ADG1433 (LFCSP and TSSOP) and ADG1434 (LFCSP only) enables or disables the device. When disabled, all channels are switched off. The i CMOS modular manufacturing process bines high voltage, plementary 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 devices has been able to achieve. Unlike analog ICs using a conventional CMOS process, i CMOS ponents 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. i CMOS construction ensures ultralow power dissipation, making the devices ideally suited for portable and battery-powered instruments.
