GENERAL DESCRIPTION

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).

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.
