DG2788, DG2789
Vishay Siliconix
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 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.
FEATURES
• Low voltage operation (1.65 V to 4.3 V)
• Low on-resistance - RON: 0.4 typ. at 2.7 V
• Fast switching: tON = 47 ns
tOFF = 15 ns
• miniQFN-16 package
• Latch-up current > 300 mA (JESD78)
BENEFITS
• Reduced power consumption
• High accuracy
• Reduce board space
• TTL/1.8 V logic compatible
• High bandwidth
APPLICATIONS
• Cellular phones
• Speaker headset switching
• Audio and video signal routing
• PCMCIA cards
• Battery operated systems
