Low-Voltage, Low rON, Single SPDT Analog Switch
In SC-89 Package
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 at 2.7 V), charge
injection is less than 10 pC over the entire analog range.
The switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
The DG2011 is built on Vishay Siliconix’s low voltage JI2 pro-
cess. An epitaxial layer prevents latchup.
Break-before-make is guaranteed.
The DG2011 represents a breakthrough in packaging devel-
opment 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 obtain-
ing performance comparable to SC-70 analog switch devices
available today.
As a committed partner to the community and the environ-
ment, Vishay Siliconix manufactures this product with the
lead (Pb)-free device terminations. For analog switching
products manufactured with 100 % matte tin device termina-
tions, the lead (Pb)-free “-E3” suffix is being used as a desig-
nator.
