Overview
The DG412LDJ is a CMOS analog switch IC from the Vishay Siliconix DG series, featuring four independent single-pole single-throw (SPST) channels. It operates with dual supply voltages ranging from ±3V to ±15V or a single supply up to 30V. The device offers a maximum on-resistance of 80 Ohms and supports a continuous DC switch current of 30 mA. Key timing parameters include a maximum turn-on time of 85 ns and a maximum turn-off time of 60 ns. It is housed in a 16-pin PDIP package with a power dissipation rating of 900 mW and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- CMOS technology ensures low power consumption and high input impedance.
- Four independent SPST channels provide flexible signal routing capabilities.
- Low on-resistance facilitates efficient signal transmission with minimal loss.
- Wide dual or single supply voltage operation supports diverse system requirements.
Applications
- Data acquisition systems requiring precise signal switching.
- Industrial process control for sensor signal multiplexing.
- Medical instrumentation for isolated signal path management.
- Automotive test equipment for robust analog signal handling.
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Check for end-of-life notices as availability may be restricted. Ensure storage conditions meet semiconductor standards to prevent moisture damage prior to soldering.
Selection Notes
Compare on-resistance values against signal integrity requirements for the specific application. Evaluate power dissipation limits relative to ambient temperature and PCB thermal design. Consider package type compatibility with existing board layouts. Verify supply voltage ranges match the target system's power rails to ensure proper logic level interfacing.
Part Context
This component belongs to the DG412 family of quad SPST analog switches manufactured by Vishay Siliconix. The family includes variants with different packages such as SOIC and TSSOP, and varying performance specifications like lower on-resistance or faster switching speeds. The DG412LDJ specifically denotes the PDIP package variant with standard speed characteristics.
Replacement Considerations
Direct pin-compatible substitutes include DG412DJ-E3 and DG412DY-E3. Alternative options from other manufacturers should match the 16-pin DIP/SOIC form factor and similar electrical parameters. Verify that replacement parts support the required ±15V dual supply operation and 30 mA current handling capacity.
