Product Introduction

Overview

The AD8228ARMZ-RL, produced by Analog Devices Inc., is a high-performance instrumentation amplifier known for its very high gain accuracy and low gain drift. This amplifier is designed to operate on both single and dual supplies, with a wide power supply range of ±2.3 V to ±18 V, making it suitable for applications where high common-mode input voltages are encountered. The AD8228ARMZ-RL is available in an 8-lead MSOP package and is operational over the entire industrial temperature range of −40°C to +85°C, with extended operation up to +125°C.
