8 Detailed Description

8.1 Overview

The OPA620 is a high-speed, voltage-feedback operational amplifier built with CMOS technology. It features

rail-to-rail input and output (I/O) and is suitable for applications like current sensing and high-speed signal

processing.

This amplifier features a 100MHz gain bandwidth, and 190V/µs slew rate and amplifier is a unity-gain stable and

operate as a 1V/V voltage follower.
