**ADG451BRZ-REEL: A Comprehensive Technical Overview of the High-Performance CMOS Switch**

The **ADG451BRZ-REEL** represents a pinnacle of integration within Analog Devices' portfolio of monolithic CMOS switches, engineered for precision signal routing in demanding applications. This single-pole/single-throw (SPST) switch is designed to offer designers a robust solution where **ultra-low power consumption and high switching performance** are paramount.

At the core of the ADG451BRZ-REEL is an advanced CMOS process that enables its exceptional characteristics. The device features a **break-before-make switching action**, a critical function that prevents momentary shorting between input and output during the switching transition, thereby protecting sensitive downstream components. It operates from a single supply voltage ranging from +5 V to +44 V, or from dual supplies of ±5 V to ±22 V, providing remarkable flexibility for both industrial and automotive systems.

A defining attribute of this switch is its **very low on-resistance (RON) of just 28 Ω**, which remains exceptionally flat across the entire input signal range. This low and linear RON is crucial as it minimizes signal attenuation and distortion, ensuring high fidelity in precision measurement and audio signal paths. Furthermore, the device boasts **minuscule power consumption, typically drawing less than 1 µW**, making it an ideal candidate for battery-powered and portable equipment where every microwatt counts.

The **ADG451BRZ-REEL is offered in a compact 8-lead SOIC package** and is supplied on a 7-inch reel, streamlining the pick-and-place assembly process for high-volume manufacturing. Its TTL/CMOS-compatible digital inputs simplify interface logic with modern microcontrollers and FPGAs. The robust design ensures a high degree of latch-up immunity and incorporates electrostatic discharge (ESD) protection, safeguarding the device during handling and operation.

Typical applications are found in a wide array of fields, including:

* **Precision Data Acquisition Systems** for multiplexing analog signals.

* **Automotive Sensor Modules** and battery management systems (BMS).

* **Communication Infrastructure** for signal routing and gain switching.

* **Medical Instrumentation** where reliability and low power are non-negotiable.

* **Audio and Video Switching** equipment requiring minimal distortion.

**ICGOOODFIND**: The ADG451BRZ-REEL stands out as a superior CMOS switch, masterfully balancing ultra-low power dissipation, a compact form factor, and robust switching performance, making it an indispensable component for advanced electronic designs.
