Product Introduction

Overview

The AD8644ARZ, produced by Analog Devices Inc., is a quad 18 V operational amplifier designed for single-supply operation. It is part of the AD8614/AD8644 family, which is optimized for LCD monitor applications. These amplifiers are known for their high performance, including a 5.5 MHz bandwidth, rail-to-rail inputs and outputs, and a high slew rate of 7.5 V/μs. The AD8644ARZ is particularly suited for applications requiring high output drive and capacitive load handling.
