Product Introduction

Overview

The AD8620BRZ-REEL, produced by Analog Devices Inc., is a precision, very low noise, low input bias current operational amplifier. It is part of the AD8610/AD8620 family, known for its high performance and stability. The AD8620 is manufactured using the XFCB (eXtra fast complementary bipolar) process, which combines dielectrically isolated N-channel JFET technology and thin film resistors to achieve high precision and low noise. This amplifier is ideal for applications requiring high accuracy, low noise, and fast settling times.
