DG2037/2038/2039

New Product

Low-Voltage, Low rON, Dual SPST Analog Switch

FEATURES

D Low Voltage Operation (1.8 V to 5.5 V) D Low On-Resistance - r

DS(on

): 3.0 W

D Fast Switching - 12 ns D Low Charge Injection - Q

: 10 pC

INJ

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 (r

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.

BENEFITS

D Reduced Power Consumption D Simple Logic Interface D High Accuracy D Reduce Board Space

Vishay Siliconix

APPLICATIONS

D Cellular Phones D Communication Systems D Portable Test Equipment D Battery Operated Systems D Sample and Hold Circuits

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.
