Maxim Integrated MAX5487EUD+ Dual 256-Position, Non-Volatile, Linear Taper Digital Potentiometer

The MAX5487EUD+ from Maxim Integrated is a high-performance digital potentiometer that offers a compact and precise solution for adjusting and controlling voltages in a wide range of electronic applications. This dual, 256-position potentiometer features a linear taper, which ensures smooth and consistent changes in resistance. With its non-volatile memory, the MAX5487EUD+ retains the last position before power-off, providing a reliable start-up position upon power cycling.

Designed with versatility in mind, this digital potentiometer operates from a single +2.7V to +5.5V supply voltage, making it suitable for both portable and fixed power supply designs. Its SPI interface allows for easy digital control, enabling integration with microcontrollers and other digital systems for precise adjustments.

The MAX5487EUD+ comes in a compact 14-pin TSSOP package, providing a space-saving solution for applications where board space is at a premium. The device's integrated features include 50kΩ end-to-end resistance, which is ideal for a broad range of applications, including audio signal control, calibration adjustments, and feedback systems.

Key features of the MAX5487EUD+ include:

• 256 linear-taper tap points
• Non-volatile EEPROM to store settings
• Single supply voltage operation from +2.7V to +5.5V
• Low temperature coefficient of 35ppm/°C
• Simple SPI-compatible serial interface
• Power-on recall—potentiometer wiper positions are stored in EEPROM
• 14-pin TSSOP package

This digital potentiometer is an excellent choice for designers looking for a reliable and precise variable resistance solution. The MAX5487EUD+'s non-volatile storage and digital interface make it an ideal component for automated systems that require repeatable and accurate settings. Whether it's for volume control in audio applications, setting operational parameters in industrial systems, or fine-tuning in precision instrumentation, the MAX5487EUD+ delivers consistent performance and quality expected from Maxim Integrated products.
