Maxim Integrated MAX4518ESD+ Analog Multiplexer

The MAX4518ESD+ is a precision, monolithic, dual 4-channel analog multiplexer from Maxim Integrated that offers an ideal solution for routing analog and digital signals in various applications. This high-performance device is designed to operate with a single supply voltage ranging from +4.5V to +36V or dual supplies of ±4.5V to ±20V, making it highly versatile for different circuit environments.

Featuring low on-resistance (less than 100 ohms) and over 15V/μs switching speeds, the MAX4518ESD+ ensures minimal signal distortion and fast transition times, which is critical for high-speed data acquisition systems and audio signal routing. The on-resistance is matched between channels to within 2.5 ohms and is flat (1.5 ohms) over the specified signal range, providing excellent linearity and low signal attenuation.

This device integrates charge injection and capacitance compensation, which significantly reduces the off-channel leakage current, enhancing the performance of sample-and-hold circuits and ensuring high precision in measurement applications. The MAX4518ESD+ also features a 44V maximum V_NO/V_COM voltage, which allows it to handle higher signal levels without compromising device integrity or performance.

With its extended temperature range of -40°C to +85°C, the MAX4518ESD+ is suitable for demanding environments and can reliably operate in industrial and automotive applications. The product is offered in a 14-pin SOIC package, ensuring ease of integration into existing designs without requiring significant board space.

Maxim Integrated has designed the MAX4518ESD+ with a break-before-make switching action, which prevents momentary shorting when switching between channels. This feature is crucial for protecting sensitive analog signals and maintaining data integrity during the switching process.

In summary, the MAX4518ESD+ from Maxim Integrated is a high-quality, reliable solution for analog signal multiplexing needs in various electronic systems. Its robust design, low on-resistance, and fast switching capabilities make it an excellent choice for precision analog applications in industrial, communication, and automotive industries.
