**ADG619SRJZ-EP-RL7: A High-Performance, Radiation-Hardened Analog Switch for Critical Space Applications**

In the demanding environment of space, electronic components must operate with unwavering reliability under extreme conditions, including exposure to ionizing radiation and wide temperature fluctuations. The **ADG619SRJZ-EP-RL7** is a radiation-hardened, single-pole double-throw (SPDT) analog switch engineered specifically to meet these stringent requirements. This device stands as a critical solution for signal routing in satellite systems, space probes, and other high-reliability aerospace and defense applications where failure is not an option.

This analog switch is designed to operate with a **wide supply voltage range from 1.8 V to 5.5 V**, making it exceptionally versatile for interfacing with both modern low-voltage and legacy systems. Its **low on-resistance (typically 2.5 Ω)** and flatness ensure minimal signal distortion and power loss, which is paramount for preserving the integrity of analog signals and precision measurements. Furthermore, the switch features **break-before-make switching action**, preventing momentary shorting between input channels during switching transitions and enhancing system safety.

The **"EP"** suffix denotes its membership in the EliteSiS radiation-hardened family, which is qualified to MIL-PRF-38535 Class V and manufactured on a specialized process. The device is **immune to latch-up** and is guaranteed to tolerate **total ionizing dose (TID) levels up to 100 krad(Si)** and single-event effects (SEE), ensuring long-term functionality in harsh radiation environments. The **RL7** tape and reel packaging is optimized for automated assembly processes, streamlining manufacturing for high-volume production.

A key advantage of the ADG619SRJZ-EP-RL7 is its **ultra-low power consumption**, which is a critical parameter for power-sensitive space missions. Its compact footprint and robust performance make it an ideal choice for a multitude of functions, including **power sequencing, channel isolation, and sensor signal routing** in data acquisition systems.

**ICGOODFIND:** The ADG619SRJZ-EP-RL7 is a premier radiation-hardened analog switch that delivers exceptional performance, reliability, and integration for the most critical space and military systems. Its combination of low on-resistance, wide voltage operation, and superior radiation tolerance makes it an indispensable component for designers building next-generation, mission-critical hardware.
