MAX4518CEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4518CEE+T is a precision, monolithic CMOS analog multiplexer housed in a 16-pin QSOP package. It features four independent channels with an on-resistance of less than 100 ohms and matching within 4 ohms between channels. The device operates on a single supply from +2.7V to +15V or bipolar supplies from ±2.7V to ±8V. Key electrical parameters include a maximum transition time of 250ns, charge injection below 5pC, and off-leakage current under 2nA at +85°C. 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 'CEE' corresponds to the 16-pin QSOP package and the commercial temperature range (0°C to +70°C). Confirm that the '+T' designation indicates tape-and-reel packaging if required by the assembly process. Ensure the component meets RoHS standards as indicated by the plus sign in the part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact 4-channel multiplexer is needed with tight resistance matching requirements. The MAX4518 offers superior channel-to-channel matching compared to standard switches. Consider the MAX4519 if only two channels are required in the same footprint. Verify that the operating voltage range aligns with the system's single or dual supply rails.

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 normally-open channels, whereas the MAX4519 provides two dual 2-channel configurations. Both share similar electrical characteristics and fabrication processes.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness for the MAX4518?

The on-resistance flatness is guaranteed to be 10 ohms maximum over the specified analog signal range.

How does the MAX4518 handle overvoltage conditions?

Signals on any terminal exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added for additional protection if power-supply sequencing cannot be guaranteed.

Is the MAX4518 compatible with standard logic families?

Yes, the device features CMOS-logic input compatibility and is also TTL-compatible, providing reduced input loading.
