DG2037/2038/2039 New Product Vishay Siliconix Low-Voltage, Low rON, Dual SPST Analog Switch FEATURES BENEFITS APPLICATIONS D D D D D D D D D D D D D D D D Low Voltage Operation (1.8 V to 5.5 V) Low On-Resistance - rDS(on): 3.0 W Fast Switching - 12 ns Low Charge Injection - QINJ: 10 pC Low Power Consumption TTL/CMOS Compatible SOT23-8 and MSOP-8 Packages Reduced Power Consumption Simple Logic Interface High Accuracy Reduce Board Space Cellular Phones Communication Systems Portable Test Equipment Battery Operated Systems Sample and Hold Circuits DESCRIPTION The DG2037/2038/2039 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): 3.0 W @ 2.7 V) and small physical size, the DG2037/2038/2039 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2037/2038/2039 are built on Vishay Siliconix’s new high density low voltage 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. FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATIONDG2037 DG2037, MSOP-8 DG2037.
