LTM2985 Datasheet Isolated High ACcuracy Digital Temperature Measurement System

Manufacturer: Analog Devices

Overview: LTM2985 Isolated High Accuracy Digital Temperature Measurement System with.

General Description

The LTM®2985 measures a wide variety of temperature sensors and digitally outputs the result, in °C or °F, with 0.1°C accuracy and 0.001°C resolution.

The LTM2985 can measure the temperature of virtually all standard (Type B, E, J, K, N, S, R, T) or custom thermocouples, automatically pensate for cold junction temperatures and linearize the results.

The device can also measure temperature with standard 2-, 3- or 4-wire RTDs, thermistors and diodes.
