Overview

Directly Digitizes 2-, 3-, or 4-Wire RTDs, Thermocouples, Thermistors, and Diodes
On-Chip EEPROM (LTC2986-1) Stores Channel Configuration Data and Custom Coefficients
Single 2.85V to 5.25V Supply
10 Flexible Inputs Allow Interchanging Sensors
Automatic Thermocouple Cold Junction Compensation
Built-In Standard and User-Programmable Coefficients for Thermocouples, RTDs and Thermistors
Measures Negative Thermocouple Voltages
Automatic Burn Out, Short-Circuit and Fault Detection
Buffered Inputs Allow External Protection
Simultaneous 50Hz/60Hz Rejection
Includes 15ppm/°C (Max) Reference
Includes Special Protection Modes

The LTC2986 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 LTC2986 can measure the temperature of virtually all standard (Type B, E, J, K, N, S, R, T) or custom thermocouples, automatically compensate 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. The LTC2986 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor.

The LTC2986/LTC2986-1 are 10-channel software and pin-compatible versions of the 20-channel LTC2983/LTC2984. Additional features include special modes that enable easy protection in universal multi-sensor applications, custom tables for generic ADC readings, and direct temperature readout from active analog temperature sensors. The LTC2986-1 is the EEPROM version of the LTC2986.
