DESCRIPTION
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.
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
DG2721 is fully RoHS complaint.
