Product Introduction

Overview

The AD5262BRUZ20-RL7 is a dual-channel, 256-position, digitally controlled variable resistor (VR) device produced by Analog Devices Inc. This device functions as a digital potentiometer, providing the same electronic adjustment capabilities as a mechanical potentiometer or variable resistor. It features a fixed resistor with a wiper contact that can be adjusted via a digital code loaded into an SPI-compatible serial-input register. This makes it versatile for various applications requiring precise and programmable resistance adjustments.
