**ADG621BRMZ-REEL: A High-Performance, Low-Voltage Dual SPST CMOS Switch**

In the realm of modern electronic design, the demand for efficient and reliable signal routing components is paramount. The **ADG621BRMZ-REEL** stands out as a critical solution, engineered to meet the rigorous requirements of today's low-voltage, portable, and battery-operated applications. This device is a **high-performance, dual single-pole/single-throw (SPST) CMOS switch** that excels in precision signal switching with minimal power consumption.

A defining feature of the ADG621BRMZ-REEL is its **operation down to a 1.8V single supply**, making it exceptionally suited for modern low-voltage systems found in communications infrastructure, medical instrumentation, and automated test equipment. Despite its low-voltage capability, it maintains a low on-resistance of just 2.5 Ohms (typical) and exhibits **remarkably flat on-resistance performance** across the input signal range. This ensures minimal signal distortion and superior fidelity in audio, video, and data transmission paths.

The device is designed with **break-before-make switching action**, which is crucial for preventing momentary shorting between channels during the switching process, thereby protecting sensitive downstream components. Furthermore, it boasts an **ultra-low power consumption** and is constructed with advanced CMOS technology, which provides not only high switching speed but also a very high off-isolation and low leakage currents. This combination of traits makes it an ideal choice for multiplexing, signal gating, and bus switching applications where signal integrity is non-negotiable.

Housed in a compact 8-lead MSOP package, the ADG621BRMZ-REEL is also optimized for space-constrained PCB designs. Its **TTL/CMOS compatible logic inputs** allow for seamless interfacing with modern microcontrollers and digital processors, simplifying system design and integration. The part is offered in a tape and reel (REEL) packaging format, streamlining the assembly process for high-volume manufacturing.

ICGOODFIND: The ADG621BRMZ-REEL is a superior analog switch that masterfully balances low-voltage operation, minimal signal path distortion, and robust integration capabilities. It is an exemplary component for designers who prioritize signal integrity, power efficiency, and space savings in their advanced electronic systems.
