ADG1434 LFCSP_VQ GENERAL DESCRIPTION The ADG1433 and ADG1434 are monolithic industrial-CMOS (iCMOS) 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 ADG1433 (LFCSP and TSSOP packages) and ADG1434 (LFCSP package only) is used to enable or dis...
