DG2727, DG2728, DG2729 Vishay Siliconix 0.65-Ω, Low Voltage, Negative Swing Capable, Dual SPST Analog Switch DESCRIPTION FEATURES The DG2727, DG2728, and DG2729 are 0.6 Ω dual SPST analog switches. When Sx are used as signal input, these devices support AC-coupled audio signals with single rail power supply. Audio signals can swing below ground down to V+ - 4.3 V. Built on Vishay Siliconix’s sub-micro CMOS technology, the DG2747/2748/2749 achieve 0.6 Ω on-resistance and 0.2 Ω flatness at 2.7 V power supply. Its total harmonic distortion is 0.006 % (frequency ranges 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 78 MHz. Select pin of control logic can tolerate voltage above power supply up to 4.3 V. It has guaranteed 1.2 V logic high for the power supply 2.7 V to 4.3 V range. This makes 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-8L package (1.4 mm x 1.4 mm x 0.55 mm) and operate over - 40 °C to + 85 °C extended temperature range. • Halogen-free according to IEC 61249-2-21 definition • Wide operation voltage range: 1.6 V to 4.3 V • Low 0.6 Ω (typical at 2.7 V) on-resistance • Guaranteed logic high threshold: Vth(high) = 1.2 V at V+ = 4.3 V • - 82 dB crosstalk and - 76 dB off-isolation at 100 kHz • 250 MHz, - 3 dB bandwidth • 0.006 % total harmonic distortion • > 250 mA latch up current per JESD78 • > 8 kV ESD/HBM per MIL-STD 883 (method 3015) • Compliant to RoHS directive 2002/95/EC BENEFITS • Ultra small miniQFN-8L package of 1.4 mm x 1.4 mm x 0.55 mm • High fidelity audio switch • Reed relay replacement • Low power consumption APPLICATIONS • • • • • • • Cellular phones GPS and portable media player Audio and video signal routing Modems Hard drives and computer peripherals Low voltage data-acquisition circuits Medical and test equipment FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG2727 miniQFN-8L DG2728 miniQFN-8L V+ V+ (Top View) 8 IN1 1 7 (Top View) 8 IN2 IN1 1 7 IN2 S1 2 6 S2 5 D2 Gx S1 D1 2 6 S2 3 5 D2 Kx Pin 1 Pin 1 D1 Device Marking: Gx for DG2727 x = Date/Lot Traceability Code 3 4 4 GND GND DG2729 miniQFN-8L Top View Device Marking: Kx for DG2728 x = Date/Lot Traceability Code Top View V+ 8 (Top View) IN1 1 7 IN2 S1 2 6 S2 D1 3 5 D2 Lx Pin 1 4 Device Marking: Lx for DG2729 x = Date/Lot Traceability Code GND Top View Document Number: 69049 S09-0557-Rev.
