Overview
The DG412FEUE+T is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features rail-to-rail signal handling and fault protection capabilities. The device operates on dual supply voltages ranging from ±4.5 V to ±20 V or a single supply of 9 V to 36 V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a typical turn-on time of 250 ns, and a typical turn-off time of 125 ns. It is housed in a TSSOP-16 surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrated fault protection circuitry safeguards against input voltage excursions exceeding the power supply rails.
- Rail-to-rail signal switching capability allows for full dynamic range operation across the entire supply voltage span.
- CMOS technology ensures low power consumption and high input impedance suitable for precision signal routing.
Applications
- Data acquisition systems requiring robust signal switching with overvoltage tolerance
- Industrial process control instrumentation involving hazardous environment signals
- Medical equipment signal conditioning paths needing reliable isolation and protection
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides traceability certificates matching the Analog Devices part number to avoid counterfeit risks during procurement.
Selection Notes
Select this variant for applications demanding both high-voltage fault protection and rail-to-rail signal integrity. Compare on-resistance specifications against other DG412 series members if lower resistance is required. Verify that the TSSOP-16 footprint aligns with existing PCB layout constraints before finalizing the design choice.
Part Context
This component belongs to the DG412 family of improved quad SPST analog switches. It shares architectural similarities with the DG411 and DG413 but distinguishes itself through enhanced fault protection features not present in standard variants. The FEUE+ designation specifies the lead-free, halogen-free TSSOP-16 package configuration.
Replacement Considerations
The DG412EVE serves as a functional equivalent lacking the integrated fault protection feature. The DG412DY+ offers similar performance in a SOIC-16 package. Verify pin compatibility and thermal characteristics when substituting these alternatives in existing designs.
