DG401B, DG403B, DG405B Vishay Siliconix Low-Power, High-Speed CMOS Analog Switches DESCRIPTION FEATURES The DG401B, DG403B, DG405B 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 silicongate 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, DG403B, DG405B 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. • • • • • • • • 44 V supply max rating ± 15 V analog signal range On-resistance - RDS(on): 23 Low leakage - ID(on): 40 pA Fast switching - tON: 100 ns Upgrade to DG401B, DG403B, DG405B TTL, CMOS compatible Single supply capability BENEFITS • Wide dynamic range • Break-before-make switching action (DG403B only) • Simple interfacing APPLICATIONS • • • • Audio and video switching Sample-and-hold circuits Test equipment PBX, PABX FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG401B Dual-In-Line and SOIC D1 NC NC NC NC NC NC D2 1 16 S1 2 15 IN1 3 14 4 13 5 12 VGND Two SPST Switches per Package TRUTH TABLE Logic Switch 0 OFF 1 ON NC V+ 6 11 7 10 IN2 8 9 S2 Logic “0” 0.8 V Logic “1” 2.4 V Top View Document Number: 73069 S11-0179-Rev.

The system will therefore store the most positive analog input experienced. 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 Reset SW2 ein – A1 + + A3 – SW1 R1 + A2 – DG401B eout C1 Figure 12. Positive Peak Detector Vishay Siliconix maintains worldwide manufacturing capability.
