Overview
The ADG5433WBRUZ is a monolithic industrial CMOS analog switch produced by Analog Devices Inc. This device features three independently selectable single-pole, double-throw (SPDT) switches. It is designed to provide low on-resistance and on-resistance flatness, making it ideal for applications where low distortion is critical, such as data acquisition and gain switching.
The ADG5433WBRUZ operates with either dual or single power supplies. For bipolar analog signals, it can be operated from dual supplies up to ±22 V, and for unipolar signals, it can operate from a single-rail power supply up to 40 V. The device includes an enable input (EN) that allows all channels to be switched off when disabled.
