DG2747, DG2748, DG2749 Vishay Siliconix 0.4-Ω, Low Voltage, Dual SPST Analog Switch DESCRIPTION FEATURES The DG2747, DG2748, and DG2749 are high performance, low on-resistance analog switches of dual SPST configuration. Built on Vishay Siliconix's sub-micro CMOS technology, the DG2747, DG2748, DG2749 achieve switch on-resistance of 0.4 Ω at 2.7 V V+ and 0.3 Ω at 4.3 V V+. It provides 0.1 Ω flatness at 2.7 V V+, and total harmonic distortion to 0.03 % (frequency range 20 Hz to 20 kHz). It achieves - 72 dB off-isolation and - 100 dB crosstalk at 100 kHz. Its - 3 dB bandwidth is up to 93 MHz. It can switch signals with amplitudes of up to VCC to be transmitted in either direction. The select pins of the control logic can tolerate voltages above V+. Logic high is 1.4 V to make it compatible with many low voltage digital control circuits. Combining wide operation voltage, low power, high speed, low on-resistance and small physical size, the DG2747, DG2748, DG2749 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2747, DG2748, DG2749 come in a small miniQFN-8 lead package (1.4 x 1.4 x 0.55 mm). As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations and is 100 % RoHS compliant. • Wide operation voltage range: 1.6 V to 4.3 V • Low on-resistance: 0.4 Ω typ. at 2.7 V • Low voltage logic threshold: Vth(high) = 1.4 V at V+ = 3 V • - 100 dB crosstalk at 100 kHz • > 250 mA latch up current per JESD78 • Switch exceeds 7 kV ESD/HBM RoHS COMPLIANT BENEFITS • • • • Ultra small miniQFN8 package of 1.4 x 1.4 x 0.55 mm High fidelity audio switch Reed relay replacement Low power consumption APPLICATIONS • • • • • Cellular phones Portable media player GPS PCMCIA cards Medical and test equipment FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG2747 miniQFN-8L DG2748 miniQFN-8L V+ V+ (Top View) 8 IN1 1 7 (Top View) 8 IN2 IN1 1 7 IN2 COM1 2 6 COM2 NC1 3 Dx COM1 NO1 2 3 6 COM2 5 NO2 Ex Pin 1 Device Marking: Dx for DG2747 x = Date/Lot Traceability Code Pin 1 4 5 4 GND GND Top View Top View NC2 Device Marking: Ex for DG2748 x = Date/Lot Traceability Code DG2749 miniQFN-8L V+ 8 (Top View) IN1 1 7 IN2 COM1 2 6 COM2 NC1 3 5 NC2 Fx Pin 1 4 Device Marking: Fx for DG2749 x = Date/Lot Traceability Code GND Top View Document Number: 69977 S09-0396-Rev.
