DESCRIPTION

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 (t ON: 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 perform ance, break-before-make is guaranteed for the SPDT configur ations. 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 wit hout the inherent dynamic range limitations. The three devices in this series are differentiated by the type of switch action as shown in the functional block diagrams.

Room = 25 °C, Full = as determined by the operating temperature suffix. c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. e. Guaranteed by design, not subject to production test. f. VIN = input voltage to perform proper function. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The output of A 2 is fed back to A 3 and compared to the analog input ein. If ein > eout the output of A3 is high keeping SW1 closed. This allows C1 to charge up to the analog input voltage. When ein goes below eout A3 goes negative, turning SW1 off. The system will therefore store the most positive analog input experienced. Vishay Siliconix maintains worldwide manufacturing capability.
