Product Introduction

Overview

The AD5290YRMZ50-R7, produced by Analog Devices Inc., is a high-performance, compact digital potentiometer. This device is part of the AD5290 series and is designed to perform the same electronic adjustment functions as mechanical potentiometers, variable resistors, and trimmers, but with enhanced resolution, solid-state reliability, and superior temperature stability. It features a 256-position digital potentiometer configuration with a linear taper and is housed in a compact MSOP-10 package. The device operates over an automotive temperature range of −40°C to +125°C, making it suitable for a wide range of applications requiring precise and reliable electronic adjustments.
