Product Introduction

Overview

The AD592CN is a precision IC temperature transducer produced by Analog Devices Inc. It is a two-terminal monolithic integrated circuit that provides an output current proportional to absolute temperature. This device operates over a wide range of supply voltages, acting as a high impedance temperature-dependent current source of 1 µA/K. The AD592CN is known for its high accuracy, stability, and repeatability, making it an ideal substitute for older sensor technologies such as thermistors, RTDs, and thermocouples.
