Maxim Integrated's MAX5499ETE+ Precision Digital Potentiometer

The MAX5499ETE+ from Maxim Integrated is a high-performance, dual, nonvolatile linear-taper digital potentiometer that is designed to provide precise and reliable digital control over resistance settings. This compact component is an ideal solution for applications requiring digitally controlled resistance adjustments. The MAX5499ETE+ is encapsulated in a space-saving 16-pin TQFN package, making it suitable for space-constrained applications.

This digital potentiometer operates from a wide voltage range of 2.7V to 5.5V and offers a resistance range of 50kΩ, which is split between two independent potentiometers. Each potentiometer can be individually configured through an SPI-compatible serial interface, providing flexibility and ease of use. The MAX5499ETE+ offers 256 taps, which allows for fine granularity in resistance adjustments, ensuring a high degree of precision in setting the resistance value.

One of the key features of the MAX5499ETE+ is its nonvolatile memory, which allows the potentiometer to retain the last programmed resistance value even after the power is cycled. This ensures consistent performance and is particularly useful in applications where maintaining specific settings is crucial. The device also includes a 50kΩ end-to-end resistance with a typical temperature coefficient of 35ppm/°C, which helps maintain stability over a wide temperature range.

The digital potentiometer is widely used in applications such as adjustable power supplies, LCD screen calibration, and audio volume control. Its robust design ensures reliability and performance, making it a preferred choice for designers who require a high-quality digital potentiometer for their circuits.

For added protection, the MAX5499ETE+ includes integrated fault protection features such as write protection and brown-out reset, which prevent accidental changes to the resistance settings during undesirable voltage conditions. With its combination of precision, flexibility, and reliability, the MAX5499ETE+ from Maxim Integrated is an excellent choice for any application needing digitally controlled variable resistance.
