DG2537DQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2537DQ-T1-GE3 is a precision dual SPST analog switch from the Vishay Siliconix DG2537/DG2538/DG2539 series, designed for low-voltage applications. It operates on dual power supplies ranging from ±1.8 V to ±2.75 V and supports asymmetrical rails. The device features a maximum on-resistance of 4.5 Ω, with typical values around 2.5 Ω. Key electrical parameters include a -3 dB bandwidth of 366 MHz, turn-on time of 35 ns maximum, and turn-off time of 20 ns maximum. It offers low leakage current (±0.25 nA typical), charge injection of 2.2 pC typical, and off-capacitance of 8 pF typical. Power supply current is less than 2 µA. The component is housed in an MSOP-10 package and operates within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix T1-GE3 against the manufacturer's official documentation to confirm reel packaging and RoHS compliance status. Confirm the NRND (Not Recommended for New Designs) lifecycle status with the supplier before initiating procurement. Ensure the MSOP-10 package dimensions match the target PCB footprint requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual supply operation between ±1.8 V and ±2.75 V is required. The DG2537 variant specifically provides Normally Open (NO) configuration. Compare its 4.5 Ω max on-resistance and 366 MHz bandwidth against single-supply alternatives like the DG72x series if voltage constraints allow. Verify that the MSOP-10 package fits the available board space compared to smaller options like TDFN8.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2537/DG2538/DG2539 family of precision analog switches. These devices are engineered alongside the DG721/722/723 series but utilize dual power supplies instead of single supply. The family shares characteristics such as low parasitic capacitance, pico-amp level leakage, and flat on-resistance, targeting high-precision data acquisition and test equipment applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult the manufacturer's datasheet or technical support for recommended alternates, noting the NRND status of this specific component.
