Maxim Integrated DS1847B-050+TR Dual Digital Potentiometer

The DS1847B-050+TR from Maxim Integrated is a versatile dual digital potentiometer designed for applications requiring a variable resistance solution. This integrated circuit (IC) features two digitally-controlled potentiometers (POTs) that are individually adjustable through a 2-wire serial interface. The digital nature of this device ensures precision and repeatability in adjustment, which is crucial for maintaining consistency in performance across various conditions and over time.

Each potentiometer in the DS1847B-050+TR has 256-position and operates with a resistance value of 50kΩ, providing a wide range of adjustment for fine-tuning circuit parameters such as voltage, current, or signal amplitude. This makes it an ideal choice for applications in audio processing, feedback control systems, and calibration of sensors where precise resistance tuning is necessary.

The device operates from a 2.7V to 5.5V power supply, which allows for flexibility in various system designs, from low-voltage portable devices to higher voltage industrial equipment. The DS1847B-050+TR also features non-volatile memory (EEPROM) to store the wiper position, ensuring that the last programmed settings are retained even after the power is cycled, eliminating the need for recalibration at each startup.

Engineered with reliability in mind, the DS1847B-050+TR is available in a compact TSSOP-14 package, making it suitable for space-constrained applications. The “+TR” suffix indicates that this product is offered in tape and reel packaging, which is optimized for automated pick-and-place assembly processes, thereby reducing manufacturing time and costs.

As with many Maxim Integrated products, the DS1847B-050+TR is designed to meet the stringent requirements of industrial applications. It provides robust performance in a wide temperature range, ensuring that the device operates effectively in various environmental conditions.

In summary, the DS1847B-050+TR dual digital potentiometer from Maxim Integrated is a high-performance, reliable solution for designers looking to incorporate digitally controlled variable resistors into their electronic designs. Its precision, flexibility, and ease of use make it an excellent choice for a broad range of applications.
