| DG401B/403B/405B New Product Vishay Siliconix Low-Power, High-Speed CMOS Analog Switches FEATURES D D D D D D D D 44-V Supply Max Rating "15-V Analog Signal Range On-Resistance--r DS(on): 23 W Low Leakage--ID(on): 40 pA Fast Switching--tON: 100 ns Upgrade to DG401/403/405 TTL, CMOS Compatible Single Supply Capability BENEFITS D Wide Dynamic Range D Break-Before-Make Switching Action (DG403B only) D Simple Interfacing APPLICATIONS D D D D Audio and Video Switching Sample-and-Hold Circuits Test Equipment PBX, PABX DESCRIPTION The DG401B/403B/405B monolithic analog switches are replacements for the popular DG401/403/405 analog switches and provide improved performance, combining high speed (tON: 100 ns, typ) with low power consumption make the DG401B series ideal for portable and battery powered 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. 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. The DG401B has two independent SPST switches. The DG403B has four SPST switches in NO/NC combinations. The DG405B has four switches in two SPST pairs. (See Functional Block Diagrams and Pin Configurations on pages 1 and 2.) The DG401B/403B/405B is available in both 16-pin plastic dip and 16-pin SOIC packages. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured with 100% matte tin device terminations, the lead (Pb)-free "--E3" suffix is being used as a designator.

A, 10-Jan-05 DG401B/403B/405B New Product 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.
