Maxim Integrated DS1267S-100/T&R Digital Potentiometer

The DS1267S-100/T&R from Maxim Integrated is a versatile digital potentiometer that provides a reliable solution for adjusting and controlling resistance in a wide range of electronic applications. This compact and robust component is designed for applications where precise resistance tuning is required, such as in volume controls, filter adjustments, or power-supply adjustments.

The DS1267S-100/T&R features two digitally controlled, 256-position potentiometers in one integrated circuit. Each potentiometer can be programmed individually through a 3-wire serial interface, which allows for easy integration with microcontrollers and other digital systems. This level of control makes it an excellent choice for automated adjustments where manual tuning is impractical or undesirable.

With a resistance value of 100kΩ, this digital potentiometer is suitable for a wide range of signal levels. Its high-resolution adjustment capability enables fine tuning for precise applications. The DS1267S-100/T&R operates from a 5V supply voltage, making it compatible with many standard digital systems.

Encased in a surface-mount SOIC package, the DS1267S-100/T&R is designed for space-saving applications and is well-suited for modern PCB layouts. The “T&R” designation indicates that this product is provided in tape and reel packaging, which is ideal for automated assembly processes, ensuring efficient handling and placement during manufacturing.

Key features of the DS1267S-100/T&R include:

• Two 100kΩ potentiometers in one IC
• 256 wiper positions for fine resolution
• 5V operating voltage
• 3-wire serial interface for easy digital control
• Nonvolatile storage of wiper position
• SOIC packaging for compact design
• Tape and reel packaging for automated manufacturing

Maxim Integrated's DS1267S-100/T&R is a reliable and precise component that meets the needs of designers looking to add digital control to their resistive applications. Its integration of two potentiometers with nonvolatile memory ensures consistent performance and durability, making it a smart choice for both prototyping and mass production.
