Overview
The DG412DJ+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open configuration and operates within a temperature range of -40°C to +85°C in a 16-pin Plastic DIP package. The device supports single supplies from +10V to +30V or bipolar supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 45Ω, an on-resistance match between channels of 3Ω max, and on-resistance flatness of Δ4Ω max. Switching times are specified with a maximum turn-on time of 175ns and a maximum turn-off time of 145ns. The component exhibits low charge injection of 10pC max and logic supply current of 1µA max.
Feature Summary
- Features improved on-resistance matching between channels and guaranteed on-resistance flatness over the signal range.
- Provides rail-to-rail signal handling capability while maintaining low power consumption.
- Ensures high electrostatic discharge tolerance of 2000V minimum per Method 3015.7.
- Compatible with TTL and CMOS logic levels for flexible interface integration.
Applications
- Sample-and-Hold Circuits
- Communication Systems
- Test Equipment
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm that the procurement channel provides genuine components from Analog Devices Inc. or Maxim Integrated. Ensure the received parts match the specified 16-pin Plastic DIP format and meet the required industrial temperature standards before integration into production systems.
Selection Notes
Select this component when a quad SPST switch with a normally open state is required. The device is suitable for applications demanding low on-resistance variation and high ESD protection. Verify that the system voltage requirements fall within the supported single or dual supply ranges. Consider the 16-pin DIP package constraints for PCB layout and thermal dissipation during the design phase.
Part Context
This part belongs to the DG411/DG412/DG413 family of improved analog switches. The DG412 variant specifically utilizes a normally open configuration, distinguishing it from the normally closed DG411 and the mixed-state DG413. All members share the same redesigned silicon-gate process architecture, offering enhanced performance metrics compared to legacy industry-standard equivalents.
