Maxim Integrated MAX14662ETI+ Beyond-the-Rails Multiplexer

The MAX14662ETI+ is a highly versatile and advanced 16:1 precision analog multiplexer from Maxim Integrated, designed to cater to a variety of applications requiring high-performance signal routing. This component stands out with its Beyond-the-Rails™ capability, allowing signal voltages to extend beyond the power supply rails, thereby offering a greater range of signal handling and flexibility.

Constructed with a focus on reliability and efficiency, the MAX14662ETI+ operates with a single supply voltage ranging from +1.8V to +5.5V, or a dual supply from ±1.8V to ±5.5V, which makes it suitable for both portable and stationary applications. The device features low on-resistance (Ron) of 275Ω (max) and channel-to-channel matching of 4Ω (max), ensuring minimal signal distortion and excellent performance consistency across channels.

One of the key attributes of the MAX14662ETI+ is its Beyond-the-Rails capability, which allows it to pass signals up to ±6V independent of the supply voltage. This feature is particularly beneficial in scenarios where the multiplexer needs to handle a wide range of analog signals without the need for level shifting or external components, simplifying design and reducing overall system cost.

The MAX14662ETI+ also boasts a low crosstalk performance of -93dB (typ) and off-isolation of -85dB (typ), which minimizes interference between channels and preserves the integrity of the signal being routed. Additionally, the device has an ESD protection of ±4kV Human Body Model (HBM), which safeguards it against electrostatic discharges during handling and operation.

Available in a compact 28-pin TQFN package with an operating temperature range of -40°C to +125°C, the MAX14662ETI+ is an ideal solution for applications such as data acquisition systems, battery-powered devices, communication systems, and audio/video signal routing. Its robust design and advanced features ensure that it can meet the stringent requirements of modern electronic systems while providing designers with a flexible and high-performance multiplexing solution.
