DG2539DQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2539DQ-T1-GE3 is a precision dual SPST analog switch from the DG2537/DG2538/DG2539 family, manufactured by Vishay Siliconix. It operates on dual power supplies ranging from ±1.8 V to ±2.75 V and supports asymmetrical rails. The device features a typical on-resistance of 2.5 Ω with low flatness, ensuring minimal signal distortion. Key electrical parameters include a maximum on-resistance of 4.5 Ω, a -3 dB bandwidth of 366 MHz, and a maximum supply current of 2 µA. It functions within an operating temperature range of -40 °C to +85 °C and is housed in an MSOP-10 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and compliance status. Confirm that the dual supply voltage requirements align with the target application design before procurement. Check for any recent product change notifications or obsolescence notices directly from Vishay to ensure long-term availability and consistency.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual supply operation between ±1.8 V and ±2.75 V is required. The DG2539 variant specifically provides normally closed and normally open contacts, distinguishing it from the DG2537 (NO only) and DG2538 (NC only). Ensure the system can accommodate the MSOP-10 package dimensions and thermal dissipation limits specified in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2537/DG2538/DG2539 series of precision analog switches designed for healthcare and metering applications. These devices are engineered to offer low parasitic capacitance and pico-amp level leakage currents. The series complements the single-supply DG72x family by providing dual-supply options for bipolar signal processing needs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2537DQ-T1-GE3 and DG2538DQ-T1-GE3 are pin-compatible members of the same family. The DG2537 offers NO contacts only, while the DG2538 offers NC contacts only. Verify if the specific contact configuration matches the circuit design requirements before substituting.
