Product Introduction

Overview

The AD8402ARZ10-REEL, manufactured by Analog Devices Inc., is a dual-channel, 256-position digitally controlled variable resistor (VR) device. This component performs the same electronic adjustment function as a mechanical potentiometer or variable resistor. It features two independent variable resistors in a space-saving 14-lead SOIC surface-mount package. Each variable resistor includes a fixed resistor with a wiper contact that taps the fixed resistor value based on a digital code loaded into the controlling serial input register. The device operates over an extended industrial temperature range of −40°C to +125°C, making it suitable for various applications requiring precise and programmable resistance control.
