| New Product DG2037/2038/2039 Vishay Siliconix Low-Voltage, Low rON, Dual SPST Analog Switch 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 at 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. FEATURES * * * * * * * Low Voltage Operation (1.8 V to 5.5 V) Low On-Resistance - rDS(on): 3.0 Fast Switching - 12 ns Low Charge Injection - QINJ: 10 pC Low Power Consumption TTL/CMOS Compatible SOT23-8 and MSOP-8 Packages BENEFITS * * * * Reduced Power Consumption Simple Logic Interface High Accuracy Reduce Board Space APPLICATIONS * * * * * Cellular Phones Communication Systems Portable Test Equipment Battery Operated Systems Sample and Hold Circuits FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION - DG2037 DG2037, MSOP-8 NO1 COM1 IN2 GND 1 2 3 4 Top View Device Marking: 2037 8 7 6 5 V+ IN1 COM2 NO2 IN1 V+ NO2 COM2 1 2 3 4 DG2037.

Typical values are for design aid only, not guaranteed nor subject to production testing. d. Guarantee by design, nor subjected to production test. e. VIN = input voltage to perform proper function. f. Not production tested. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. www.vishay.com 4 Document Number: 72359 S-71035-Rev.
