Maxim Integrated MAX5479ETE+T Digital Potentiometer

The MAX5479ETE+T from Maxim Integrated is a high-performance, nonvolatile, dual 256-position digital potentiometer that offers a compact and precise solution for adjusting and controlling voltages in a wide variety of applications. This digital potentiometer is designed to operate with a single supply voltage ranging from 2.7V to 5.5V or a dual supply voltage of ±2.7V, making it versatile for both portable and stationary applications.

One of the key features of the MAX5479ETE+T is its nonvolatile memory, which allows the device to retain the wiper position even after power is removed. This is particularly useful in applications where a specific calibration or setting must be maintained without the need for constant reprogramming. The device is available in a compact 16-pin TQFN package, which is ideal for space-constrained applications.

The MAX5479ETE+T offers a digital interface for wiper control, employing a three-wire SPI-compatible serial interface that allows for easy integration into most microcontroller-based systems. This interface makes it possible to adjust the wiper position with precision and ensures reliable communication between the digital potentiometer and the host controller.

With an end-to-end resistance of 10kΩ, the MAX5479ETE+T can be used in a variety of configurations, including a variable resistor or a voltage divider, depending on the application's requirements. The device's robust construction ensures it can withstand harsh operating conditions, and its extended temperature range of -40°C to +125°C makes it suitable for industrial environments.

Typical applications for the MAX5479ETE+T include adjustable power supplies, LCD screen calibration, audio volume control, and other systems requiring precise resistance tuning. Its high reliability and ease of use make it an excellent choice for designers looking to add digital control to their analog circuits without compromising on performance.

Overall, the MAX5479ETE+T is a testament to Maxim Integrated's commitment to providing innovative and reliable solutions for digital potentiometer needs across various industries.
