> 500 MHz, - 3 dB Bandwidth; Dual SPDT Analog Switch
DESCRIPTION
FEATURES
•
•
•
•
Wide operation voltage range
Low on-resistance, 5.7 Ω (typical at 3 V)
Low capacitance, 5.6 pF (typical)
- 3 dB high bandwidth with 5 pF load:
> 500 MHz (typical)
DG2721 is a low Ron, high bandwidth analog switch
configured in dual SPDT.
It achieves 5.7 Ω switch on resistance, greater than
500 MHz - 3 dB bandwidth with 5 pF load, and a channel to
channel crosstalk and Isolation at - 49 dB.
RoHS
COMPLIANT
Fabricated with high density sub micro CMOS process, the
DG2721 provides low parasitic capacitance, handles
bidirectional signal flow with minimized phase distortion.
Guaranteed 1.3 V logic high threshold makes it possible to
interface directly with low voltage MCUs.
The DG2721 is designed for a wide range of operating
voltages from 2.7 V to 4.3 V that can be driven directly from
one cell Li-ion battery. On-chip protection circuit protects
again fault events when signals at “com” pins goes beyond
V+.
Latch up current is greater than 300 mA, as per JESD78, and
its ESD tolerance exceeds 8 kV.
Packaged in ultra small miniQFN-10 (1.4 mm x 1.8 mm x
0.55 mm), it is ideal for portable high speed mix signal
switching application.
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product with
lead (Pb)-free device termination. The miniQFN-10 package
has a nickel-palladium-gold device termination and is
represented by the lead (Pb)-free "-E4" suffix to the ordering
part number. The nickel-palladium-gold device terminations
meet all JEDEC standards for reflow and MSL rating.
As a further sign of Vishay Siliconix's commitment, the

Notes:
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.
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.
