MAX4520EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4520EUA+T is a single-pole/single-throw (SPST) analog switch in an 8-pin µMAX package. It features fault protection up to ±36V with power on and ±40V with power off, ensuring rail-to-rail signal handling. The device operates from dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. Key electrical parameters include a maximum on-resistance of 160Ω, off-leakage current of 0.5nA at +25°C, and turn-on/turn-off times of 500ns and 175ns respectively under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs handle overvoltage events without transitioning the output state
• Rail-to-Rail signal capability allows full voltage range operation across supplies
• Output clamps to appropriate supply voltage during faults to prevent transition glitches
• Compatible with TTL and CMOS logic levels for direct interface

Analog Switches, Multiplexers, Demultiplexers Applications

• Data Acquisition Systems
• Industrial and Process-Control Systems
• Avionics Equipment
• Automated Test Equipment (ATE)
• Redundant and Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUA+T' against official documentation to confirm the 8-pin µMAX package and tape-and-reel delivery format. Ensure the component meets RoHS compliance standards as indicated by the '+' designation. Cross-reference the manufacturer's part number guide to validate that ordering suffixes do not alter the functional specifications or pinout configuration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required on the analog input path while maintaining low on-resistance. The MAX4520 is specifically designed for normally open applications, contrasting with the MAX4510 which is normally closed. Consider the ±40V fault tolerance and rail-to-rail performance for high-voltage signal switching environments where standard switches might fail.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4510/MAX4520 family of rail-to-rail, fault-protected SPST analog switches manufactured by Analog Devices Inc./Maxim Integrated. The series is characterized by its unique parallel FET construction, which provides superior on-resistance compared to traditional series FET designs while maintaining robust fault protection capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4510EUA+ serves as a functional substitute within the same package if a normally closed configuration is acceptable instead of the normally open topology. Verify that the replacement matches the specific package type and temperature range requirements.
