LTC2986ILX-1#PBF

Thermal Management Overview

The LTC2986ILX-1#PBF is a multi-sensor digital temperature measurement system in a 48-lead LQFP package. It features a single 2.85V to 5.25V supply and provides ±0.1°C accuracy with 0.001°C resolution. The device digitizes thermocouples, RTDs, thermistors, and diodes via an SPI interface. It includes on-chip EEPROM for storing configuration data and custom coefficients.

Thermal Management Feature Summary

• Digitizes standard and custom thermocouples with automatic cold junction compensation
• Measures 2-, 3-, or 4-wire RTDs and thermistors using built-in excitation current sources
• Includes on-chip EEPROM for non-volatile storage of channel configurations and calibration coefficients
• Provides fault detection including burn-out, short-circuit, and overvoltage protection

Thermal Management Applications

• Industrial process control systems requiring multi-point temperature monitoring
• HVAC equipment utilizing direct sensor digitization
• Medical instrumentation demanding high accuracy and low noise
• Automotive thermal management applications

Thermal Management Procurement Notes

Verify the specific suffix '-1' confirms the inclusion of onboard EEPROM, as this distinguishes it from the base LTC2986 model. Ensure the 'LX' designation matches the required LQFP-48 plastic package variant. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement specifications.

Thermal Management Selection Notes

Select this component when designing systems that require simultaneous measurement of diverse sensor types without external multiplexers. The integrated linearization and polynomial calculation capabilities reduce microcontroller processing load. Verify that the operating temperature range meets the environmental requirements of the target application.

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 devices. The ILX-1 variant specifically targets industrial environments with a -40°C to +85°C operating range and includes non-volatile memory for persistent configuration settings.

Thermal Management Replacement Considerations

The base LTC2986ILX#PBF is functionally identical but lacks the EEPROM feature found in the ILX-1 version. For higher channel counts, the LTC2983 or LTC2984 serve as compatible upgrades.
