Maxim Integrated DS1867S-010+T&R Dual Digital Potentiometer

The DS1867S-010+T&R from Maxim Integrated is a versatile, dual digital potentiometer designed to offer precision and reliability in a variety of electronic applications. This compact component is a part of Maxim's renowned series of programmable potentiometers that provide a digital solution to adjust and calibrate system parameters electronically, replacing mechanical potentiometers and trimmers.

The DS1867S-010+T&R features two independently programmable potentiometers, each with 256-position wiper settings, allowing for fine-tuned adjustments. The device operates with a supply voltage range of 2.7V to 5.5V, making it suitable for both 3V and 5V systems. It comes in a small 14-pin SOIC package, ensuring a minimal footprint on the PCB and is ideal for applications where space is at a premium.

One of the key benefits of the DS1867S-010+T&R is its non-volatile memory (EEPROM), which stores the wiper position for future use, even after the power is turned off. This ensures that the device retains its last configuration and can resume operation without the need for recalibration upon power-up. The wiper position can be adjusted via a 3-wire serial interface, which is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, providing flexibility and ease of integration into existing systems.

The DS1867S-010+T&R is designed for applications that require precise voltage adjustments or variable resistance settings. These include but are not limited to LCD screen brightness and contrast control, parameter adjustments in audio applications, and system calibration in industrial settings. The device's robust design ensures reliable performance over its entire operating temperature range of -40°C to +85°C.

Offered in tape and reel packaging (T&R), the DS1867S-010+T&R is ideal for automated manufacturing processes, ensuring efficient handling and placement during PCB assembly. Maxim Integrated's commitment to quality and performance makes the DS1867S-010+T&R a smart choice for designers looking to add digital potentiometer functionality to their next project.
