Overview
The ADG733BRUZ is a low-voltage, CMOS analog switch produced by Analog Devices Inc. This device features three independently selectable SPDT (single pole, double throw) switches, making it ideal for various applications requiring high performance and low power consumption. The ADG733 is designed on an enhanced submicron process, providing low power dissipation, high switching speed, very low on-resistance, high signal bandwidths, and low leakage currents. It is particularly suited for battery-powered and portable instruments due to its operating supply range of +1.8 V to +5.5 V and dual ±2.5 V supply rails.
