Product Introduction

Overview

The AD8131ARM, produced by Analog Devices Inc., is a low-cost, high-speed differential driver designed for the transmission of high-speed signals over various media, including twisted pair and coax cables. This component is a significant advancement over traditional op-amps, particularly for driving signals over long lines or for driving differential input ADCs. It features a unique internal feedback mechanism that ensures output gain and phase matching, reducing radiated EMI and suppressing harmonics. The AD8131ARM is manufactured on Analog Devices' next-generation XFCB bipolar process and is available in both SOIC and MSOP packages, operating over a temperature range of -40°C to +125°C.
