Low Voltage, Low On-Resistance, Dual DPDT/Quad SPDT
Analog Switch
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 mm x 1.8 mm 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.
