Product Details

The ADG1634L is a monolithic industrial CMOS (iCMOS®) analog switch comprising four independently selectable single-pole, double-throw (SPDT) switches, respectively.

All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input on the ADG1634L is used to enable or disable the device. When disabled, all channels are switched off. The switch is enabled with a Logic 1 EN input, while the INx input defines the state of the SPDT switch (see Table 12 in the data sheet).

The ultralow on resistance and on-resistance flatness of the switch makes it an ideal solution for data acquisition and gain switching applications, where low distortion is critical. iCMOS construction ensures ultra low power dissipation, making the device ideally suited for portable and battery-powered instruments.

An external VL supply provides flexibility for lower logic control. The ADG1634L is both 1.2 V and 1.8 V JEDEC standard compliant.
