**ADG5412BCPZ-REEL7: High-Voltage, Latch-Up Immune, Quad SPST Switch from Analog Devices**

In the realm of precision signal routing and high-voltage switching, the **ADG5412BCPZ-REEL7** from Analog Devices stands out as a robust and highly reliable solution. This quad, single-pole/single-throw (SPST) switch is engineered to meet the demanding requirements of industrial, instrumentation, and automotive systems where **high-voltage operation and exceptional reliability** are non-negotiable.

A defining characteristic of this switch is its **latch-up immunity**, a critical feature that ensures continuous operation and protects the system from catastrophic failure. Built on Analog Devices' proprietary iCMOS® (industrial CMOS) process technology, the ADG5412BCPZ-REEL7 can handle bipolar signals up to **±22 V** and operate from dual supplies ranging from ±5 V to ±22 V or a single supply from 8 V to 44 V. This flexibility makes it an ideal component for a wide array of applications, including **automated test equipment (ATE), data acquisition systems, and avionics**.

The device integrates four independent switches, each offering a break-before-make switching action. This design prevents signal channel shorting during switching transitions, thereby safeguarding downstream circuitry. Furthermore, the ADG5412BCPZ-REEL7 features **very low on-resistance (35 Ω max)** and flat on-resistance across the entire signal range, which minimizes distortion and ensures signal integrity for precision analog and digital signals.

Housed in a compact 16-lead LFCSP package, this switch is also designed for performance in harsh environments. It offers an **extended operating temperature range of -40°C to +125°C**, making it suitable for industrial and automotive applications. The combination of high performance, integration, and robustness provides designers with a component that enhances system reliability while simplifying design complexity.

**ICGOODFIND:** The ADG5412BCPZ-REEL7 is a superior quad SPST switch that delivers high-voltage handling, latch-up immunity, and low on-resistance in a space-saving package. It is an excellent choice for designers seeking to improve signal routing accuracy and system robustness in demanding industrial and automotive environments.
