DG2727, DG2728, DG2729 Document Number: 69049 S09-0557-Rev. A, 13-Apr-09 www.vishay.com 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 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.

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. 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.
