DG611/612/613 Vishay Siliconix High-Speed, Low-Glitch D/CMOS Analog Switches Fast Switching-- tON: 12 ns Low Charge Injection: 2 pC Wide Bandwidth: 500 MHz 5-V CMOS Logic Compatible Low rDS(on): 18 Low Quiescent Power : 1.2 nW Single Supply Operation Improved Data Throughput Minimal Switching Transients Improved System Performance Easily Interfaced Low Insertion Loss Minimal Power Consumption Fast Sample-and-Holds Synchronous Demodulators Pixel-Rate Video Switching Disk/Tape Drives DAC Deglitching Switched Capacitor Filters GaAs FET Drivers Satellite Receivers The DG611/612/613 feature high-speed low-capacitance lateral DMOS switches. Charge injection has been minimized to optimize performance in fast sample-and-hold applications. switching FETs with low-power CMOS control logic and drivers. An epitaxial layer prevents latchup. The DG611 and DG612 differ only in that they respond to opposite logic levels. The versatile DG613 has two normally open and two normally closed switches. It can be given various configurations, including four SPST, two SPDT, one DPDT. Each switch conducts equally well in both directions when on and blocks up to 16 Vp-p when off. Capacitances have been minimized to ensure fast switching and low-glitch energy. To achieve such fast and clean switching performance, the DG611/612/613 are built on the Vishay Siliconix proprietary D/CMOS process. This process combines n-channel DMOS For additional information see Applications Note AN207 (FaxBack number 70605).

Charge Injection FIGURE 4. Crosstalk High-Speed Sample-and-Hold In a fast sample-and-hold application, the analog switch characteristics are critical. A fast switch reduces aperture uncertainty. A low charge injection eliminates offset (step) errors. A low leakage reduces droop errors. The CLC111, a fast input buffer, helps to shorten acquisition and settling times. A low leakage, low dielectric absorption hold capacitor must be used. Polycarbonate, polystyrene and polypropylene are good choices. The JFET output buffer reduces droop due to its low input bias current. (See Figure 5.) GaAs FET Drivers Figure 7 illustrates a high-speed GaAs FET driver. To turn the GaAs FET on 0 V are applied to its gate via S1, whereas to turn it off, -8 V are applied via S2. This high-speed, low-power driver is especially suited for applications that require a large number of RF switches, such as phased array radars. Pixel-Rate Switch Windows, picture-in-picture, title overlays are economically generated using a high-speed analog switch such as the DG613. For this application the two video sources must be sync locked. The glitch-less analog switch eliminates halos. (See Figure 6.) Document Number: 70057 S-00399--Rev.
