0.39 , Low-RON, Ultra-Low Distortion,
Compact DPDT Analog Switch
DESCRIPTION
FEATURES
The DG2751 is a compact, low resistance, ultra-low
distortion double pole double throw (DPST) analog switch.
•
•
•
•
The DG2751 features a flat 0.39 ON resistance over the
analog signal range from (V+) - 5.5 V to V+, supporting
bi-directional negative signal swing. The design brings
superior signal fidelity by eliminating the distortion caused
by double hump switch resistance character of conventional
analog switches.
•
•
•
•
•
•
•
•
The DG2751 operates over a voltage range from 3 V to
5.5 V. Because of its low current consumption, it can be
powered directly by a GPIO. When V+ power is off, all switch
pins are of high impedance mode.
Shunt switches are integrated at normally close (NOn)
channels to discharge the AC-coupling capacitance at the
terminals.
2.3 V to 5.5 V single supply operation
Low resistance: 0.39 / typ. at 2.7 V
Highly flat and matched RON
Low parasitic capacitance, CON = 31 pF,
COFF = 30 pF
High bandwidth: 290 MHz
Guaranteed logic high 1.2 V, logic low 0.3 V
Break before make switching
Signal swing over V+ capable
Power down protection
Latch up current: 300 mA (JESD78)
ESD/HBM: > 8 kV
Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
The part is controlled by a single bit, S, which can interface
with 1.2 V low voltage I/O. Switch ON/OFF is of
break-before-make (BBM).
•
•
•
•
•
•
•
•
•
The DG2751 is available in ultra-compact 1.2 mm x 1.2 mm,
9-bump WCSP package, and operate over the -40 °C to
+85 °C extended temperature range.

b. All leads welded or soldered to PC board.
c. Derate 12 mW/°C above 70 °C.
d. Package thermal resistances were obtained using the method described in JEDEC® specification JESD51-7.
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.

a. Room = 25 °C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, not subjected to production test.
e. VIN = input voltage to perform proper function.
f. Crosstalk measured between channels.
g. When NC is off, NC is connected to the 100 shunt resistor.
