DG401/403/405 Vishay Siliconix Low-Power, High-Speed CMOS Analog Switches DESCRIPTION FEATURES 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. • • • • • • 44 V Supply Max Rating ± 15 V Analog Signal Range On-Resistance - rDS(on): 30 Ω Low Leakage - ID(on): 40 pA Fast Switching - tON: 75 ns Ultra Low Power Requirements - PD: 0.35 µW • TTL, CMOS Compatible • Single Supply Capability 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. Pb-free Available RoHS* COMPLIANT BENEFITS • Wide Dynamic Range • Break-Before-Make Switching Action • Simple Interfacing Each switch conducts equally well in both directions when on, and blocks up to 30 V peak-to-peak when off. Onresistance is very flat over the full ± 15 V analog range, rivaling JFET performance without the inherent dynamic range limitations. APPLICATIONS • • • • • • The three devices in this series are differentiated by the type of switch action as shown in the functional block diagrams.

H, 11-Jun-07 DG401/403/405 Vishay Siliconix APPLICATIONS Peak Detector: A3 acting as a comparator provides the logic drive for operating SW1. The output of A2 is fed back to A3 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.
