Product Introduction

Overview

The AD8671AR-REEL7, produced by Analog Devices Inc., is a high-precision operational amplifier known for its very low noise, low offset voltage, and low input bias current. This amplifier is part of the AD8671/AD8672/AD8674 family, which is renowned for its ultralow noise, high precision, speed, and stability. The AD8671 is particularly suited for applications requiring high accuracy and low noise, such as high-quality PLL filters, precision filters, medical and analytical instrumentation, and professional quality audio.
