DG411FEUE

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411FEUE+ is a quad, single-pole single-throw (SPST) normally closed CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a 16-pin TSSOP surface-mount package with an exposed pad. The device operates on a single supply voltage ranging from 10 V to 30 V or dual supplies of ±4.5 V to ±20 V. Key electrical specifications include a maximum on-resistance of 45 Ohms, a maximum power dissipation of 755 mW, and a maximum supply current of 400 µA. The unit supports a continuous DC switch current of 20 mA and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Quad SPST configuration providing four independent signal paths in a compact surface-mount footprint.
• Normally closed topology ensures default signal continuity when control logic is inactive.
• CMOS construction enables low power consumption while maintaining robust switching performance.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal routing
• Battery-operated equipment due to low quiescent current
• Automatic test and measurement instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering code matches the required package variant and temperature grade for your design constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed state is required for signal integrity during power-down conditions. Compare the 45 Ohm on-resistance against circuit load requirements to ensure acceptable voltage drop. Verify that the TSSOP-16 package dimensions fit the available PCB real estate.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411 family of improved quad SPST analog switches. It serves as a surface-mount alternative to through-hole DIP variants like the DG411CJ+, offering similar electrical performance in a smaller form factor suitable for high-density board layouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411EUE+ is a verified substitute within the same series. Check datasheets for any differences in on-resistance tolerance or thermal resistance between the FEUE and EUE suffixes before swapping.
