Overview
The ADG734BRUZ, produced by Analog Devices Inc., is a low-voltage, CMOS analog switch that features four independently selectable SPDT (single pole, double throw) switches. This device is designed on an enhanced submicron process, offering low power dissipation, high switching speed, very low on-resistance, high signal bandwidths, and low leakage currents. It is ideal for battery-powered, portable instruments due to its low power consumption and wide operating supply range of 1.8 V to 5.5 V, as well as dual ±2.5 V supplies.
