**The ADG608BNZ: A Comprehensive Guide to Analog Devices' 8:1 CMOS Multiplexer**

In the world of electronic signal routing, the multiplexer stands as a fundamental component, enabling the selection of one of many input signals to a single output. Among these, the **ADG608BNZ from Analog Devices** represents a pinnacle of integration and performance for 8-channel analog switching. This device is a monolithic, CMOS-based single-pole, eight-throw (SP8T) analog multiplexer, designed to handle a wide range of analog and digital signals with exceptional precision and reliability.

Engineered for versatility, the ADG608BNZ operates over a broad power supply range, from **±5V to as high as ±22V** for dual supplies, or a single supply from +8V to +44V. This flexibility makes it suitable for a vast array of applications, including industrial process control, automotive systems, medical instrumentation, and audio/video signal routing. Its CMOS construction ensures it possesses the highly desirable traits of **very low power consumption** and high switching speed, critical for battery-powered and portable equipment.

A key feature of this multiplexer is its **break-before-make switching action**. This design ensures that the connection to one channel is completely broken before a new connection is established to the next selected channel. This prevents momentary shorting between two input signals, which could be catastrophic in sensitive analog circuits. Furthermore, the ADG608BNZ boasts **TTL and CMOS-compatible digital inputs**. This allows it to be directly interfaced with a wide range of modern microcontrollers, FPGAs, and logic families without requiring additional level-shifting circuitry, simplifying system design.

The analog performance of the ADG608BNZ is equally impressive. It offers **low on-resistance (typically 100Ω)** that remains very flat across the entire analog signal range, ensuring minimal distortion of the switched signal. Coupled with its extremely low leakage currents, these characteristics make it an excellent choice for precision data acquisition systems where signal integrity is paramount. The device is available in a compact 16-lead PDIP and SOIC_N package, making it easy to integrate into both through-hole and surface-mount PCB designs.

**ICGOODFIND Summary:** The Analog Devices ADG608BNZ is a highly robust and versatile 8:1 CMOS analog multiplexer. Its combination of a wide voltage range, low power consumption, TTL/CMOS compatibility, and excellent analog signal fidelity makes it an **outstanding choice for designers** who need reliable and precise signal routing in demanding environments.
