Analog Devices Introduces Industry’s First Analog Fault Detection and Protection Switch Family for Analog Input/Output Modules in Harsh Environments

The new switches also offer a best-in-class combination of robustness and precision performance in a small package, suiting them for precision instrumentation, process control and avionic signal chains. Providing up to ± 55-V over-voltage protection, coupled with a 5.5-kV HBM ESD level, these switches protect downstream system components in both power-on and power-off states, while protecting against hot-swapping and operator miss-use events. The leading-edge combination of low Ron, Ron flatness and low leakage, coupled with the removal of discrete protection components, leads to a reduction in signal distortion and system error budget. The ultra-low Ron flatness level offered by this family also minimizes system total harmonic distortion and noise performance.
