| DG2003/2004/2005 New Product Vishay Siliconix Low-Voltage Dual SPST Analog Switch FEATURES D D D D D D D Low Voltage Operation (1.8 V to 5.5 V) Low On-Resistance - rDS(on): 1.2 W Fast Switching - 14 ns Low Charge Injection - QINJ: 1 pC Low Power Consumption TTL/CMOS Compatible MSOP-8 Package BENEFITS D D D D Reduced Power Consumption Simple Logic Interface High Accuracy Reduce Board Space APPLICATIONS D D D D D Cellular Phones Communication Systems Portable Test Equipment Battery Operated Systems Sample and Hold Circuits DESCRIPTION The DG2003/2004/2005 are dual single-pole/single-throw monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, fast switching, low on-resistance (rDS(on): 1.2 W) and small physical size (MSOP-8), the DG2003/2004/2005 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2003/2004/2005 are built on Vishay Siliconix's low voltage JI2 process. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
