DG2727DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2727DN-T1-E4 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.6 V to 4.3 V and supports negative signal swings down to V+ - 4.3 V, making it suitable for AC-coupled audio applications. The device features a typical on-resistance of 0.65 Ω at 2.7 V with a maximum of 1.0 Ω at room temperature. It provides a -3 dB bandwidth of up to 252 MHz, turn-on time of 67 ns, and turn-off time of 40 ns. Packaged in a miniQFN-8L (1.4 mm x 1.4 mm) format, it functions within an extended temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability codes marked on the package. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when board space is limited due to its ultra-small miniQFN-8L footprint. It is appropriate for designs requiring negative signal swing capability without dual supplies. Verify that the control logic voltage levels align with the guaranteed logic high threshold specifications across the operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2727/2728/2729 family of low-voltage analog switches. While sharing similar electrical characteristics and packaging, the DG2727 differs from the DG2728 and DG2729 primarily in its internal logic configuration and pinout arrangement for the signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements include DG2728DN-T1-E4 and DG2729DN-T1-E4. Note that these variants possess different internal logic states and pin configurations compared to the DG2727, necessitating schematic review before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

Can the DG2727 handle signals below ground?

Yes, the device supports negative signal swings down to V+ - 4.3 V, allowing it to process AC-coupled audio signals even when powered by a single positive rail.

What is the maximum voltage allowed on the control pins?

The select pins (IN1, IN2) can tolerate voltages above the positive power supply rail up to a maximum of 4.3 V.

How does the on-resistance vary with temperature?

The on-resistance increases slightly at higher temperatures; the maximum specification rises from 1.0 Ω at room temperature to 1.15 Ω across the full -40 °C to +85 °C operating range.
