The DS1867-100 from Maxim Integrated is a versatile dual digital potentiometer that combines two digitally controlled solid-state potentiometers on a single chip. Designed to operate from a wide range of power supplies, this device is ideal for a variety of applications that require precise digital control over resistance settings.

Key Features

• Dual Potentiometer Design: Integrates two independent potentiometers, each with 256-position wiper settings, providing flexibility for dual-channel applications.
• Wide Voltage Range: The DS1867-100 operates from a 2.7V to 5.5V supply, making it suitable for both low-power and standard logic-level environments.
• Nonvolatile Memory: Wiper positions can be stored in onboard EEPROM, ensuring that the last settings are recalled upon power-up.
• Serial Interface: Features a 3-wire serial interface that allows for easy integration into existing digital systems and microcontroller-based projects.
• High Reliability: With no moving parts, the digital potentiometer provides a more reliable solution than mechanical potentiometers, particularly in harsh environments.
• Compact Package: Available in a small 14-pin TSSOP package, the DS1867-100 saves valuable board space in space-constrained applications.
