ADG1634

4.5 Ω RON ，三/四路SPDT ± 5 V ， + 12V ， + 5V和+ 3.3V开关 4.5 Ω RON, Triple/Quad SPDT ±5 V, +12 V, +5 V, and +3.3 V Switches

Product Details

The ADG1633 and 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 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. iCMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.
