GENERAL DESCRIPTION
The ADG1633 and ADG1634 are monolithic industrial
CMOS (i
CMOS®) analog switches comprising three independently selectable single-pole, double-throw (SPDT) switches and four independently selectable SPDT switches, respectively.
All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input on the ADG1633 (LFCSP and TSSOP packages) and ADG1634 (LFCSP package only) is used to enable or disable the devices. When disabled, all channels are switched off.
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 parts ideally suited for portable and battery-powered in...
