The DG401/403/405 monolithic analog switches were designed to provide precision, high performance switching of analog signals. Combining low power (0.35 µW, typ) with high speed (tON: 75 ns, typ), the DG401 series is ideally suited for portable and battery powered industrial and military applications. Built on the Vishay Siliconix proprietary high-voltage silicon-gate process to achieve high voltage rating and superior switch on/off performance, break-before-make is guaranteed for the SPDT configurations. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks up to 30 V peak-to-peak when off. On resistance is very flat over the full ± 15 V analog range, rivaling JFET performance without the inherent dynamic range limitations.
