Overview
The DG441DY+T is a quad single-pole single-throw (SPST) analog switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10 V to 30 V for single supplies, or ±4.5 V to ±20 V for dual supplies. The device features a maximum on-resistance of 85 Ohms and supports a DC switch current of 30 mA. Switching performance includes a maximum turn-on time of 250 ns and a maximum turn-off time of 120 ns. It is housed in a 16-pin SOIC-Narrow package with surface-mount installation. The component functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches within a single monolithic CMOS structure.
- Supports both single and dual power supply configurations for flexible system integration.
- Provides high-speed signal switching capabilities suitable for data acquisition applications.
Applications
- Data acquisition systems requiring multiple channel selection
- Signal routing in instrumentation equipment
- Process control modules
Procurement Notes
Verify the specific suffix designation when sourcing components, as packaging formats vary between tape-and-reel and tube configurations depending on the exact part number variant. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure that the selected package type aligns with the intended surface-mount assembly process requirements.
Selection Notes
Select this component when a quad SPST configuration is required within a compact surface-mount footprint. Evaluate the 85 Ohm on-resistance limit against the application's signal integrity requirements. Consider the 10 V minimum supply voltage constraint during power budget calculations. Verify thermal dissipation limits relative to the expected load current and ambient operating conditions.
Part Context
This component belongs to the DG441 series of improved quad SPST analog switches. It shares functional similarities with other devices in the family, such as the DG441CY+, differing primarily in operational temperature ranges and packaging styles. The series represents a standard solution for general-purpose analog signal switching in industrial and commercial electronics.
Replacement Considerations
The DG441CY+ serves as a compatible alternative within the same product family. Selection between these variants should be based on specific packaging preferences and required operating temperature specifications rather than functional differences.
