0.4-Ω Low-Voltage Dual SPDT Analog Switch
DESCRIPTION
FEATURES
The DG2531/DG2532 is a sub 1-Ω (0.4 Ω at 2.7 V) dual
SPDT analog switches designed for low voltage applications.
•
•
•
•
•
Low Voltage Operation (1.8 V to 5.5 V)
Low On-Resistance - rON: 0.4 Ω at 2.7 V
- 69 dB OIRR at 2.7 V, 100 kHz
MSOP-10 Package
The DG2531/DG2532 has on-resistance matching (less than
0.05 Ω at 2.7 V) and flatness (less than 0.2 Ω at 2.7 V) that
are guaranteed over the entire voltage range. Additionally,
low logic thresholds makes the DG2531/DG2532 an ideal
interface to low voltage DSP control signals.
ESD Protection > 2000 V
BENEFITS
•
•
•
•
•
Reduced Power Consumption
The DG2531/DG2532 has fast switching speed (on/off time
at 40 and 35 ns) with break-before-make guaranteed. In the
On condition, all switching elements conduct equally in both
directions. Off-isolation and crosstalk is - 69 dB at 100 kHz.
High Accuracy
Reduce Board Space
1.6-V Logic Compatible
High Bandwidth
The DG2531/DG2532 is built on Vishay Siliconix’s high-den-
sity low voltage CMOS process. An eptiaxial layer is built in
to prevent latchup. The DG2531/DG2532 contains the addi-
tional benefit of 2000 V ESD protection.
APPLICATIONS
•
•
•
•
•
•
Cellular Phones
Speaker Headset Switching
Audio and Video Signal Routing
PCMCIA Cards
Packaged in space saving MSOP-10, the DG2531/DG2532
is a high performance, low rON switches for battery powered
applications.

a. Room = 25 °C, Full = as determined by the operating suffix.
b. Typical values are for design aid only, not guaranteed nor subject to production testing.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
d. Guarantee by design, nor subjected to production test.
e. VIN = input voltage to perform proper function.
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.
