Product Introduction

Overview

The LTC2986ILX#PBF, manufactured by Analog Devices Inc., is a high-precision digital temperature measurement system. This device is capable of measuring a wide variety of temperature sensors, including thermocouples (Type B, E, J, K, N, S, R, T), RTDs (2-, 3-, or 4-wire), thermistors, and diodes. It provides digital output in °C or °F with 0.1°C accuracy and 0.001°C resolution. The LTC2986 also includes excitation current sources and fault detection circuitry, making it versatile for universal multi-sensor applications.
