MAX4518EEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4518EEE+ is a precision, monolithic CMOS analog multiplexer housed in a 16-pin QSOP package. It features four independent channels with an on-resistance of 280Ω maximum at +5V single supply and less than 100Ω under dual ±5V conditions. The device supports single-supply operation from +2.7V to +15V or bipolar supplies from ±2.7V to ±8V. Key electrical characteristics include low off-leakage current (less than 2nA at +85°C), charge injection below 5pC, and transition times under 250ns. It provides electrostatic discharge protection exceeding 2000V and maintains rail-to-rail signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed on-resistance matching between channels within 4Ω
• Low power consumption with less than 300µW dissipation
• TTL and CMOS logic input compatibility for reduced loading
• Rail-to-rail signal handling across the full supply range

• Battery-Operated Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EEE indicates the -40°C to +85°C industrial temperature range and QSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure proper power-supply sequencing during installation to prevent permanent damage from overvoltage stresses beyond absolute maximum ratings.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise channel matching and low leakage are critical for data-acquisition systems. The MAX4518 variant offers four channels, whereas the MAX4519 provides two dual-channel switches. Consider the operating voltage requirements, as switching speeds increase significantly at lower supply voltages like +3V compared to +5V.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4518/MAX4519 family of low-voltage CMOS analog multiplexers manufactured by Analog Devices/Maxim Integrated. The series is designed for applications requiring high precision and fast switching in compact surface-mount packages. The EEE suffix specifically denotes the extended temperature range and plastic quad small-outline package format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4519EEE+ for dual-channel configurations. Cross-family replacements may require verification of pinout compatibility and on-resistance specifications against the original design constraints.
