DESCRIPTION
The DG2011 is a low on-resistance, single-pole/double-throw
monolithic CMOS analog switch. It is designed for low voltage
applications with guaranteed operation at 2 V. The DG2011 is
ideal for portable and battery powered equipment, requiring
high performance and efficient use of board space. In
additional to the low on-resistance (1.8 Ω @ 2.7 V), charge
injection is less than 10 pC over the entire analog range.
Break-before-make is guaranteed.
The DG2011 represents a breakthrough in packaging
development for analog switching products. The SC-89
package (1.6 x 1.6 mm2) – also know as SOT-666 in the
industry – reduces board spacing by approximately 40% while
obtaining performance comparable to SC-70 analog switch
devices available today.
The switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
As a committed partner to the community and the environment,
Vishay Siliconix manufactures this product with the
lead (Pb)-free device terminations. For analog switching
products manufactured with 100% matte tin device
terminations, the lead (Pb)-free “—E3” suffix is being used as
a designator.
The DG2011 is built on Vishay Siliconix’s low voltage JI2
process. An epitaxial layer prevents latchup.
