Product Introduction

Overview

The AD5242BRUZ1M-REEL7, manufactured by Analog Devices Inc., is a dual-channel, 256-position, digitally controlled variable resistor (VR) device. This digital potentiometer functions similarly to a mechanical potentiometer, trimmer, or variable resistor, offering a completely programmable resistance between the A terminal and the wiper, or the B terminal and the wiper. The device is available in a 16-lead TSSOP package and operates over an extended temperature range of −40°C to +105°C. It features an I²C-compatible, 2-wire serial data interface and includes extra programmable logic outputs. The AD5242BRUZ1M-REEL7 is suitable for various applications requiring precise and programmable resistance control.
