DESCRIPTION

The DG2788, DG2789 are monolithic CMOS analog

switching products designed for high performance switching

of analog signals. Combining low power, high speed, low

on-resistance and small physical size, the DG2788, DG2789

are ideal for portable and battery powered applications

requiring high performance and efficient use of board space.

The DG2788, DG2789 are built on Vishay Siliconix’s low

voltage process. An epitaxial layer prevents latchup. Break-

before-make is guaranteed.

The switch conducts equally well in both directions when on,

and blocks up to the power supply level when off. The

DG2788 is configured as a dual Double Pole Double Throw

switches while the DG2789 is configured as a Quad Single

Pole Double Throw. The DG2789 has one control pin for all

four SPDT switches and also has an enable pin that can turn

all switches off.

The DG2788 and DG2789 comes in a small miniQFN-16

lead package (2.6 x 1.8 x 0.75 mm).

As a committed partner to the community and the

environment, Vishay Siliconix manufactures this product

with the lead (Pb)-free device terminations and is 100 %

RoHS compliant.
