The MAX5402EUA+T from Maxim Integrated is a high-performance, digitally controlled potentiometer that offers a reliable solution for adjusting and controlling voltages in a wide range of electronic applications. This versatile device is packed in a compact 8-pin µMAX package, making it suitable for space-constrained applications.

Featuring a single-channel, 256-position, the MAX5402EUA+T provides precise voltage control with an end-to-end resistance of 50kΩ. It is designed for 2.7V to 5.5V operation, which allows it to be used in both low-voltage and standard 5V systems. This digital potentiometer is ideal for applications such as adjustable power supplies, gain control, and offset adjustment in a variety of electronic circuits.

The MAX5402EUA+T offers a simple and intuitive SPI interface for communication, enabling easy integration into existing designs without the need for complex programming. This digital potentiometer also features a 35ppm/°C end-to-end resistance temperature coefficient, ensuring stable performance over a wide temperature range.

One of the key advantages of the MAX5402EUA+T is its non-volatile memory (EEPROM), which allows the device to retain the last programmed wiper position when powered off. This feature is particularly useful for applications that require the potentiometer to maintain a set point between power cycles.

The MAX5402EUA+T is designed with robustness in mind, featuring a power-on-reset circuit that ensures the wiper initializes to the midscale position upon power-up, preventing unexpected outputs at startup. Additionally, it has a write-protect feature that prevents accidental changes to the wiper position, adding an extra layer of security to your design.

Maxim Integrated's commitment to quality and reliability is evident in the MAX5402EUA+T, making it a preferred choice for designers looking for a digital potentiometer that combines functionality, precision, and ease of use in a small form factor.
