DESCRIPTION
The DG2031 is a sub 1-W (0.75 W @ 2.7 V ) dual SPDT analog
switch designed for low voltage applications.
The DG2031 has on-resistance matching (less than 0.05 W @
2.7 V) and flatness (less than 0.2 W @ 2.7 V) that are
guaranteed over the entire voltage range. Additionally, low
logic thresholds makes the DG2031 an ideal interface to low
voltage DSP control signals.
The DG2031 has fast switching speed (on/off time @ 34 and
24 ns) with break-before-make guaranteed. In the On
condition, all switching elements conduct equally in both
directions. Off-isolation and crosstalk is −71 dB @ 100 kHz.
The DG2031 is built on Vishay Siliconix’s high-density low
voltage CMOS process. An eptiaxial layer is built in to prevent
latchup. The DG2031 contains the additional benefit of
2,000-V ESD protection.
Packaged in space saving MSOP-10, the DG2031 is a high
performance, low rON switch for battery powered applications.
The DG2031 is available in both standard and lead (Pb)-free
packaging. No lead is used in the manufacturing process, for
the lead (Pb)-free version, either inside the device/package or
on external terminations.

Notes:
a. Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
b. All leads welded or soldered to PC Board.
c. Derate 4.0 mW/_C above 70_C
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
