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 channels with an on-resistance of 280Ω maximum at +5V single supply and 125Ω maximum at ±5V dual supply. On-resistance matching between channels is guaranteed within 10Ω. The device operates from a single +2.7V to +15V supply or bipolar ±2.7V to ±8V supplies. Key electrical parameters include less than 2nA off-leakage current at +85°C, charge injection under 5pC, and transition times under 250ns. It provides electrostatic discharge protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the required QSOP-16 footprint. Ensure the temperature grade corresponds to the industrial range (-40°C to +85°C) specified for the EEE suffix. Cross-reference the part number with authorized distributors to ensure compliance with RoHS directives.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise channel-to-channel resistance matching is critical for the application. Consider the 280Ω on-resistance limit if operating strictly from a +5V single supply. Verify that the logic input voltage levels align with the system's TTL or CMOS standards. Evaluate the thermal dissipation requirements given the 762mW power dissipation rating in the QSOP package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4518/MAX4519 family of precision analog multiplexers. The MAX4518 variant specifically provides four independent channels, whereas the MAX4519 offers two dual-channel switches. Both share identical fabrication processes and core electrical characteristics, differing primarily in channel count and pin configuration within the same package families.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include the MAX4519EEE+, which offers dual 2-channel switching instead of four single channels. Other variants like the MAX4518CEE+ provide the same functionality but operate within a commercial temperature range (0°C to +70°C). Ensure pin compatibility and thermal ratings are verified before substitution.
