Key Features
- Cold junction compensation for 6 thermocouple types (J, K, T, E, R, S) from a single IC, eliminating discrete compensation circuits
- Under 80 µA supply current enabling always-on thermocouple measurement in battery-powered or remote data loggers
- 8-pin SOIC package minimizing PCB footprint for temperature measurement front-ends in compact instruments
- Direct voltage output proportional to cold junction temperature for easy interface with ADCs and microcontrollers
Applications
The LT1025CS8#PBF is used in industrial process controllers, laboratory temperature measurement instruments, and portable pyrometers where accurate thermocouple cold junction compensation is required. Its support for multiple thermocouple types and 80 µA current draw make it ideal for multichannel thermocouple data loggers and field calibrators powered by batteries. Engineers also integrate it into furnace controllers, HVAC system temperature monitoring, and scientific measurement equipment requiring traceable thermocouple accuracy.

Frequently Asked Questions
How does LT1025CS8#PBF simplify cold junction compensation for a K-type thermocouple signal chain?
The LT1025CS8#PBF generates a linearized voltage output proportional to its ambient temperature, matching the cold junction correction coefficient for K-type thermocouples at 10 µV/°C. This voltage can be summed directly with the thermocouple output before the ADC, eliminating the need for a separate temperature sensor, lookup table linearization, and firmware correction in the signal chain.
For a portable field calibrator running on AA batteries, how does LT1025CS8#PBF's current consumption affect runtime?
The LT1025CS8#PBF consumes under 80 µA from supplies as low as 4 V, contributing less than 0.32 mW to the instrument power budget. In a 2 x AA battery configuration providing 2500 mAh, the IC alone would run continuously for over 30,000 hours, making it negligible in overall battery life calculations for field instruments.
Can LT1025CS8#PBF support multiple thermocouple types in a multichannel logger with a single device?
Yes, the LT1025CS8#PBF provides separate output pins scaled for J, K, T, E, R, and S type thermocouples from one 8-pin SOIC device. A multichannel logger can select the appropriate output for each thermocouple channel using an analog multiplexer, avoiding the need for separate compensation ICs per channel and saving PCB area.
At what temperature range does LT1025CS8#PBF maintain accurate cold junction compensation, and is it suitable for outdoor enclosures?
The LT1025CS8#PBF operates from -40°C to +85°C ambient temperature, covering cold junction temperatures encountered in industrial outdoor enclosures, cold storage facilities, and unheated equipment cabinets. Its compensation accuracy over this range ensures thermocouple measurement errors from cold junction drift remain below 1°C in well-designed signal chains.
