Low power consumption and operating supply range of 1.8 V to 5.5 V and dual ± 2.5 V make the ADG733 and ADG734 ideal for battery powered, portable instruments. All channels exhibit break-before-make switching action preventing momentary shorting when switching channels. An EN input on the ADG733 is used to enable or disable the device. When disabled, all channels are switched OFF. These 2–1 multiplexers/SPDT switches are designed on an enhanced submicron process that provides low power dissipation yet gives high switching speed, very low on resistance, high signal bandwidths, and low leakage currents.
