Description

The AD5247BKSZ50-RL7 is a digital potentiometer from Analog Devices that falls under the category of electronic components. It provides a compact, packaged solution to carry out 128-position adjustment applications, which makes it an ideal choice for high accuracy and stability variable resistance adjustments. It performs the same electronic adjustment function as a mechanical potentiometer or a variable resistor. This device is available in four different end-to-end resistance values of 5 kΩ, 10 kΩ, 50 kΩ and 100 kΩ. It comes in a low-temperature coefficient and ultracompact SC70-6 (2 mm × 2.1 mm) package that is easy to install.
