All channels exhibit break-before-make switching action that EN prevents momentary shorting when switching channels. An input on the ADG1634-KGD is used to enable or disable the device. When disabled, all channels are switched off. The ultralow, on resistance and on-resistance flatness of this switch make the device an ideal solution for data acquisition and gain switching applications, where low distortion is critical. Its iCMOS construction ensures ultralow power dissipation, making the ADG1634-KGD ideally suited for portable and battery- powered instruments. Additional application and technical information can be found in the ADG1634 data sheet. Known Good Die (KGD): this die is fully guaranteed to data sheet specifications.
