LT1025CS8#PBF

Sensor And Detector Interfaces Overview

The LT1025CS8#PBF is a micropower thermocouple cold junction compensator manufactured by Analog Devices Inc. in an 8-lead SOIC package. It operates with a supply voltage range of 4V to 36V and draws a typical supply current of 80mA. The device provides direct thermocouple voltages for types E, J, K, R, S, and T, alongside a dedicated 10mV/°C output. Initial accuracy at 25°C is specified within a temperature error range of 0.5°C to 2.0°C depending on the specific grade. Line regulation is typically 0.02°C/V across the operating voltage range.

Sensor And Detector Interfaces Feature Summary

• Provides specialized curvature correction circuitry to match the non-linear characteristics of standard thermocouples over extended temperature ranges.
• Features low impedance outputs that remain essentially independent of power supply voltage variations.
• Utilizes wafer level and post-package trimming techniques to achieve high initial measurement accuracy.

Sensor And Detector Interfaces Applications

• Micropower thermocouple cold junction compensation
• Centigrade thermometer circuits
• Temperature compensation networks

Sensor And Detector Interfaces Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the part marking matches the datasheet specifications for the LT1025 series. Ensure the ordering suffix corresponds to the required plastic SO package variant. Check material declarations for compliance with relevant environmental standards before integration into production.

Sensor And Detector Interfaces Selection Notes

Select this component when precise cold junction compensation is required for types E, J, K, R, S, and T thermocouples. Consider the 80mA supply current and resulting thermal rise when designing the PCB layout. Ensure the operating environment stays within the 0°C to 70°C commercial temperature range. Verify that the 8-lead SOIC package fits the available board space constraints.
