LTC2986ILX#PBF

Thermal Management Overview

The LTC2986ILX#PBF is a multi-sensor high-accuracy digital temperature measurement system in a 48-lead LQFP package. It digitizes thermocouples, RTDs, thermistors, and diodes with 0.1°C accuracy and 0.001°C resolution. The device operates on a single 2.85V to 5.25V supply and features an SPI interface. It includes built-in excitation current sources, automatic cold junction compensation, and fault detection circuitry.

Thermal Management Feature Summary

• Digitizes standard thermocouples, RTDs, thermistors, and diodes directly
• Includes on-chip EEPROM for storing channel configuration and custom coefficients
• Provides automatic thermocouple cold junction compensation
• Features built-in standard and user-programmable coefficients

Thermal Management Applications

• Universal multi-sensor temperature monitoring
• Industrial process control systems
• HVAC temperature management
• Automotive thermal testing

Thermal Management Procurement Notes

Verify the specific suffix ILX indicates the industrial temperature grade (-40°C to +85°C) and the #PBF denotes lead-free packaging. Confirm the presence of the -1 suffix variant if non-volatile memory storage is required, as the base model lacks EEPROM. Ensure the ordering code matches the exact package and temperature range specifications.

Thermal Management Selection Notes

Select this component when high accuracy across multiple sensor types is required without external linearization circuits. The integrated cold junction compensation simplifies thermocouple applications. Consider the -1 version if persistent configuration storage is needed. Verify that the SPI interface timing meets the host controller requirements.

Thermal Management Part Context

This part belongs to the LTC2986 family, which serves as a software and pin-compatible alternative to the 20-channel LTC2983/LTC2984. It is designed for universal multi-sensor applications requiring direct digitization of various temperature sensing elements. The device integrates necessary signal conditioning and mathematical conversion algorithms internally.
