Maxim Integrated MAX5380LEUK+T Digital Potentiometer

The MAX5380LEUK+T is a high-performance digital potentiometer designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This versatile device is ideal for applications requiring precise resistance adjustments controlled via a digital interface. It is commonly used in settings such as adjustable power supplies, LCD screen calibration, and audio volume control, among others.

The MAX5380LEUK+T is a single-channel, nonvolatile (NV) digital potentiometer with 256-tap points, providing fine resolution for a wide range of applications. It operates from a single +2.7V to +5.5V supply, making it suitable for both portable and fixed power supply designs. The potentiometer's end-to-end resistance is 10kΩ, which is a standard value for many control and adjustment tasks.

One of the key features of this digital potentiometer is its SPI™-compatible serial interface, which allows for easy integration into microcontroller-based systems. The three-wire serial interface minimizes the number of connections required, thus simplifying the design and reducing the overall footprint of the device on the PCB.

The MAX5380LEUK+T comes in a compact SOT-23-8 package, which is ideal for space-constrained applications. Its small size does not compromise its performance or reliability, as it is designed to operate over the extended -40°C to +85°C temperature range, ensuring stable operation in a variety of environments.

Additionally, the device features a 50ppm/°C end-to-end temperature coefficient, which provides consistent performance across the entire temperature range. The wiper resistance is low, at 70Ω typical, which ensures minimal signal distortion when adjusting the wiper position.

For added convenience, the MAX5380LEUK+T includes a shutdown feature that reduces power consumption to 0.5µA (max), making it an excellent choice for battery-powered applications where power efficiency is critical.

Overall, the MAX5380LEUK+T digital potentiometer from Maxim Integrated is a robust, reliable, and precise solution for digitally controlled resistance applications. Its ease of integration, coupled with its small size and efficient power management, make it an excellent choice for designers looking to add digital control to their analog circuits.
