| DG2721 Vishay Siliconix > 500 MHz, - 3 dB Bandwidth; Dual SPDT Analog Switch DESCRIPTION DG2721 is a low Ron, high bandwidth analog switch configured in dual SPDT. It achieves 5.7 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.
