LT1025CS8#TRPBF

Sensor And Detector Interfaces Overview

The LT1025CS8#TRPBF is a micropower thermocouple cold junction compensator manufactured by Analog Devices Inc. It operates within a supply voltage range of 4V to 36V with a typical supply current of 80mA. The device provides direct outputs for Type E, J, K, R, S, and T thermocouples, alongside a dedicated 10mV/°C output. It features built-in curvature correction circuitry to maintain accuracy across wider temperature ranges. The component is housed in an 8-lead SOIC package and is rated for operation between 0°C and 70°C.

Sensor And Detector Interfaces Feature Summary

• Provides direct voltage outputs matching the Seebeck coefficients of standard thermocouple types including E, J, K, R, S, and T.
• Includes specialized curvature correction circuitry to compensate for non-linearities inherent in thermocouple characteristics over extended temperature spans.
• Features a low-impedance 10mV/°C output designed for simplified signal conditioning and system integration.

Sensor And Detector Interfaces Applications

• Thermocouple cold junction compensation in industrial measurement systems
• Centigrade thermometer circuits requiring direct temperature scaling
• Temperature compensation networks for precision thermal monitoring

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the CS8 designation corresponds to the commercial temperature grade and SOIC package variant required for the design. Ensure compatibility with existing board layouts for the 8-lead small outline package before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this component when designing systems utilizing Type E, J, K, R, S, or T thermocouples that require integrated cold junction compensation. The 80mA supply current necessitates consideration of self-heating effects; ensure adequate thermal management or lower supply voltages to minimize internal temperature rise. Verify that the operating environment remains within the specified 0°C to 70°C range for guaranteed performance.

Sensor And Detector Interfaces Part Context

The LT1025 series serves as a foundational micropower solution for thermocouple signal conditioning. The CS8 variant specifically denotes the commercial grade version packaged in an 8-lead plastic small outline (SO) format. This package option facilitates surface mount assembly while maintaining the electrical characteristics defined by the broader LT1025 family specifications.

Sensor And Detector Interfaces Replacement Considerations

Consult manufacturer documentation for alternative packages such as PDIP or CERDIP if through-hole mounting is required. No direct cross-model substitutes are confirmed in public datasheets; verify pinout and electrical parameters against any potential third-party replacements.
