MAX4518CSD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4518CSD+ is a precision, monolithic CMOS analog multiplexer housed in a 14-pin Narrow SO package. It features four independent SPST switches with an on-resistance of less than 100Ω and matching within 4Ω between channels. The device operates from a single +2.7V to +15V supply or bipolar ±2.7V to ±8V supplies. Key electrical parameters include off-leakage current below 2nA at +85°C, charge injection under 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 Procurement Notes

Verify the specific suffix 'CSD+' against official documentation to confirm the narrow SOIC package and commercial temperature range. Ensure compatibility with existing PCB footprints and soldering profiles. Cross-reference the manufacturer's latest datasheet revision to validate pin configurations and absolute maximum ratings before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise channel matching and low leakage are required in low-voltage environments. The 14-pin SO package suits space-constrained designs. Verify that the application voltage stays within the +2.7V to +15V single-supply or ±2.7V to ±8V dual-supply limits to ensure optimal performance and reliability.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4518/MAX4519 family of precision analog multiplexers manufactured by Analog Devices (Maxim Integrated). The MAX4518 variant specifically provides four independent channels, distinguishing it from the dual-channel MAX4519. Both share identical fabrication processes and core electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4518CSE+ and MAX4518CSA+. Verify package dimensions and pinout compatibility before substitution. Check if alternative suffixes indicate different temperature ranges or packaging formats.
