Overview
The DG722DQ-T1-GE3 is a Vishay Siliconix analog switch IC featuring two single-pole single-throw (SPST) channels in an MSOP-8 surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V, with a maximum on-resistance of 4.5 Ohms. The device supports a continuous DC switch current of 50 mA and draws a maximum supply current of 2 µA. Key switching parameters include a maximum turn-on time of 30 ns and a maximum turn-off time of 35 ns. It functions within a temperature range of -40°C to +85°C and has a power dissipation rating of 320 mW.
Feature Summary
- Low-voltage operation compatible with 1.8 V to 5.5 V single supplies
- Ultra-low quiescent current consumption for battery-powered applications
- Fast switching speeds with nanosecond-level transition times
- Compact MSOP-8 footprint for space-constrained designs
Applications
- Portable consumer electronics requiring low-power signal routing
- Battery-operated instrumentation and measurement devices
- Communication equipment signal path switching
- Industrial control systems with low-voltage logic interfaces
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors or secondary markets, as primary production may be limited. Ensure the ordering suffix matches the required reel quantity of 2500 units. Check for RoHS compliance documentation specific to the manufacturing batch before integration into new products.
Selection Notes
Select this component when designing circuits that require low-voltage analog switching with minimal power draw. The 4.5 Ohm on-resistance is suitable for signals where moderate insertion loss is acceptable. Consider the MSOP-8 thermal characteristics and ensure adequate PCB layout for heat dissipation given the 320 mW power dissipation limit. Verify that the input signal levels remain within the specified supply voltage boundaries to prevent damage.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix, designed for general-purpose signal switching applications. The DG722 variant specifically offers dual SPST configuration in a compact package. It complements other parts in the family like the DG723, which offers similar functionality but with different pinout or electrical characteristics. The series is known for balancing performance with low power consumption in small form factors.
Replacement Considerations
The DG722DQ-GE3 is listed as an alias part number, indicating potential compatibility without the tape-and-reel suffix. No other direct substitute part numbers are confirmed in the provided data. Evaluate alternative dual SPST analog switches if NRND status impacts long-term supply stability.
