New Product DG2037/2038/2039 Vishay Siliconix Low-Voltage, Low r , Dual SPST Analog Switch ON DESCRIPTION FEATURES The DG2037/2038/2039 are dual single-pole/single-throw Low Voltage Operation (1.8 V to 5.5 V) monolithic CMOS analog switch designed for high Low On-Resistance - r : 3.0 DS(on) performance switching of analog signals. Combining low Fast Switching - 12 ns power, fast switching, low on-resistance (r : 3.0 at DS(on) Low Charge Injection - Q : 10 pC INJ 2.7 V) and small physical size, the DG2037/2038/2039 are Low Power Consumption ideal for portable and battery powered applications requiring high performance and efficient use of board space. TTL/CMOS Compatible SOT23-8 and MSOP-8 Packages The DG2037/2038/2039 are built on Vishay Siliconixs new high density low voltage process. An epitaxial layer prevents BENEFITS latchup. Reduced Power Consumption Each switch conducts equally well in both directions when Simple Logic Interface on, and blocks up to the power supply level when off.
