Figure 2. ADG1634 TSSOP 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 ADG1634 (LFCSP package only) is used to enable or disable S1A S4A the devices. When disabled, all channels are switched off. D1 D4 S1B S4B The ultralow on resistance and on-resistance flatness of these switches make them ideal solutions for data acquisition and gain S2B S3B switching applications, where low distortion is critical. iCMOS D2 D3 construction ensures ultralow power dissipation, making the parts S2A S3A ideally suited for portable and battery-powered instruments.
