LTC2983ILX#PBF

Sensor And Detector Interfaces Overview

The LTC2983ILX#PBF is a multi-sensor 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 features 20 reconfigurable analog inputs and three simultaneous 24-bit delta-sigma ADCs driven by an internal reference. Operating on a single 2.85V to 5.25V supply, it includes automatic cold junction compensation, built-in linearization coefficients for standard sensors, and fault detection circuitry.

Sensor And Detector Interfaces Feature Summary

Sensor And Detector Interfaces Procurement Notes

Verify the specific I-grade suffix (ILX) against the required operating temperature range of -40°C to 85°C. Confirm the 48-lead LQFP package dimensions match the PCB footprint requirements. Ensure the order quantity aligns with the manufacturer's tray packaging specifications for this component variant.

Sensor And Detector Interfaces Selection Notes

Select the LTC2983ILX#PBF when applications require simultaneous measurement of diverse sensor types within a single channel count. The I-grade designation ensures performance across the industrial temperature range. Evaluate the 20-input capacity against the total number of distinct measurement points required for the design.

Sensor And Detector Interfaces Part Context

This component belongs to the LTC2983 family of high-accuracy digital temperature monitors. It serves as a central interface for complex thermal sensing architectures, replacing discrete signal conditioning circuits. The ILX suffix specifically denotes the industrial temperature grade variant within the broader product line.
