Maxim Integrated Digital Potentiometer 32-Position 50 kΩ Linear Non-Volatile Memory 3 Wire Up/Down Interface MAX5474EKA+T

Maxim Integrated MAX5474EKA+T digital potentiometer is a precision electronic component featuring 32 discrete linear positions with a resistance of 50 kΩ. Designed for use in a variety of electronic systems, this device integrates non-volatile memory that retains the wiper position after power cycling, making it ideal for stable settings in sensitive applications.

Packaged in a compact 8-pin SOT-23 surface mount form factor measuring just 3mm in length, 1.75mm in width, and 1.3mm in height, the MAX5474EKA+T is easy to integrate into PCB designs where space is limited. The device operates efficiently on a single supply voltage ranging from 2.7V to 5.25V with a very low static current consumption of only 1μA max, which is advantageous for battery-powered and low-power circuits.

With a resistance temperature coefficient of 35 ppm/°C and ratiometric temperature coefficient of 5 ppm/°C, the potentiometer maintains accurate resistance values over a wide temperature range from −40°C to +85°C, ensuring reliable performance in industrial and commercial environments. The wiper supports voltage-divider and variable-resistor configurations, offering versatility in analog signal adjustment.

Typical applications include audio volume control, liquid crystal display (LCD) screen adjustment, programmable filters, and as replacements for mechanical potentiometers, enhancing durability and precision. The device guarantees over 200,000 wiper store cycles and a data retention life of 50 years, supporting long-term reliability.

This digital potentiometer is an excellent choice for industrial automation, consumer electronics, instrumentation, and calibration systems requiring stable and programmable resistance control within a compact footprint.
