Maxim Integrated MAX5488EUD+T Dual 256-Tap Volatile Digital Potentiometer

The Maxim Integrated MAX5488EUD+T is a high-performance, dual-channel digital potentiometer designed to offer precise and reliable digital control over resistance settings. This compact and efficient component is ideal for a wide range of applications, including adjustable power supplies, LCD screen calibration, and audio signal conditioning.

Key Features

• 256 Position Settings: The MAX5488EUD+T provides 256 tap points, allowing for fine-tuning of resistance from 0 to 10kΩ, ensuring high-resolution adjustments.
• Dual Independent Channels: With two potentiometers in one package, it allows for simultaneous control of two separate circuits, saving space and reducing component count.
• Non-Volatile Memory: The device features volatile memory, which means the resistance setting is not retained upon power-down, making it suitable for applications that require a reset to a default state upon startup.
• Low Temperature Coefficient: The low temperature coefficient of 35ppm/°C ensures stable performance over a wide temperature range, maintaining accuracy and reliability.
• Serial Interface: It employs a 3-wire SPI-compatible serial interface for communication, facilitating easy integration with microcontrollers and other digital systems.
• Wide Operating Voltage: The digital potentiometer operates over a broad voltage range of 2.7V to 5.5V, making it versatile for various power environments.
• Compact Package: Housed in a compact 14-pin TSSOP package, the MAX5488EUD+T is designed for space-constrained applications.

Applications

The MAX5488EUD+T is suitable for a variety of applications that require digital control of resistance settings. It is particularly useful in:

• Automated product calibration systems
• Adjustable power supplies and regulators
• LCD panel brightness and contrast controls
• Audio equipment for volume and tone control
• Portable electronic devices

With its precise control, dual-channel operation, and easy integration, the Maxim Integrated MAX5488EUD+T digital potentiometer is an excellent choice for designers looking to add reliable and adjustable resistance settings to their electronic projects.
