.Data Sheet.co.kr DG2727, DG2728, DG2729 Vishay Siliconix 0.65-Ω, Low Voltage, Negative Swing Capable, Dual SPST Analog Switch DESCRIPTION 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 k Hz). It achieves - 72 d B off-isolation and - 100 d B crosstalk at 100 k Hz. Its - 3 d B 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 patible with many low voltage digital control circuits. bining 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 e in a small mini QFN-8L package (1.4 mm x 1.4 mm x 0.55 mm) and operate over - 40 °C to + 85 °C extended temperature range. Features - 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 d B crosstalk and - 76 d B off-isolation at 100 k Hz - 250 MHz, - 3 d B bandwidth - 0.006 % total harmonic distortion - > 250 m A latch up current per JESD78 - > 8 k V ESD/HBM per MIL-STD 883 (method 3015) - pliant to Ro HS directive 2002/95/EC BENEFITS - Ultra small mini QFN-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...
