DESCRIPTION

DG2721 is a low R on, 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 su b 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 t hat 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.

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. V IN = 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 indi cated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
