Maxim Integrated MAX5489ETE Dual 256-Tap Volatile Digital Potentiometer

The MAX5489ETE from Maxim Integrated is a high-performance, dual 256-tap, volatile digital potentiometer that offers precise voltage control in a compact package. Designed for applications requiring a variable resistance setting, this digital potentiometer is ideal for adjusting and calibrating system parameters, such as volume control in audio applications, LCD screen brightness adjustment, or fine-tuning bias voltages.

Enclosed in a 16-pin TQFN (Thin Quad Flat No leads) package with exposed pad, the MAX5489ETE operates over a wide temperature range from -40°C to +85°C, making it suitable for a broad array of industrial and consumer applications. The device integrates two independent potentiometers, each with 256 wiper tap points, allowing for precise settings.

The MAX5489ETE features a simple SPI-compatible serial interface for communication, enabling easy adjustment of the wiper position by writing to the device's wiper register. Its volatile memory ensures that the wiper position is not retained after power-off, providing a default start-up position upon each power cycle.

With its 10kΩ end-to-end resistance, the MAX5489ETE offers a smooth transition between tap points, which is critical for sensitive applications that demand high-resolution adjustments. The device's low temperature coefficient ensures stable performance across the full operating temperature range, maintaining accuracy and reliability of the system.

Key features of the MAX5489ETE include:

• Dual 256-position linear taper potentiometer
• 10kΩ end-to-end resistance
• SPI-compatible serial interface
• Wide operating temperature range: -40°C to +85°C
• Compact 16-pin TQFN package
• Low temperature coefficient for stable operation

Whether you're designing a high-fidelity audio system, precision control circuit, or need a reliable adjustable component for your next project, the MAX5489ETE provides a versatile and high-quality solution for your digital potentiometer needs.
