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.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-ADG1634LEBZ is the evaluation board for the ADG1634L. The ADG1634L contains four independent single-pole, double-throw (SPDT) switches. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.
An external VL supply pin provides logic control flexibility for lower logic controls. The ADG1634L is both 1.2 V and 1.8 V JEDEC standard compliant.
Figure 1 in the user guide shows the EVAL-ADG1634LEBZ in a typical evaluation setup. The EVAL-ADG1634LEBZ is located in the center of the evaluation board. Eight test points are included to connect to each of the source pins. Subminiature Version B (SMB) sockets are included for the drain inputs. Three screw terminals power the device. A 5-pin header is provided for user defined digital voltage, if required.
Full specifications on the ADG1634L are available in the ADG1634L data sheet available from Analog Devices, Inc., and should be consulted in conjunction with the user guide when using the EVAL-ADG1634LEBZ.
