DG723DQ-T1-GE3

Overview

The DG723DQ-T1-GE3 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 4.5 V to 24 V or dual supplies up to ±12 V. The device features a maximum on-resistance of 4.5 Ohms and supports a continuous DC switch current of 250 mA. Key electrical parameters include a 366 MHz -3dB bandwidth, 2.2 pC charge injection, and 90 dB crosstalk at 10 MHz. It is housed in an 8-pin MSOP package with a junction temperature range of -40°C to +85°C.

Feature Summary

• Dual SPST configuration for independent signal routing
• Low charge injection of 2.2 pC for high-fidelity switching
• High bandwidth of 366 MHz suitable for RF applications
• Low off-state capacitance to minimize signal leakage

Applications

• RF signal routing and switching matrices
• Audio signal path selection
• Data acquisition systems requiring low distortion
• Instrumentation front-end multiplexing

Procurement Notes

Verify the component status as discontinued before finalizing designs. Confirm that the 8-MSOP package dimensions match the target PCB footprint. Ensure the operating voltage limits are respected within the specific circuit environment to maintain reliability.

Selection Notes

Select this component when low charge injection and high bandwidth are critical requirements. Compare the 4.5 Ohm on-resistance against load impedance needs. Consider the MSOP package size constraints relative to available board space and thermal dissipation capabilities.

Part Context

This part belongs to the DG series of analog switches from Vishay Siliconix. It complements other variants like the DG722 and DG9233 by offering a balance between speed and drive capability in a compact surface-mount package.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify if newer generation switches offer improved on-resistance or lower power consumption while maintaining the same package outline.
