How To Make A Thermocouple Meter With The LTC2492

Mark Thoren - Staff Scientist Sep 15th 2008

This video explains how to use the 24-bit LTC2492 2-channel delta-sigma analog-to-digital converter with Easy Drive Input Current Cancellation to make thermocouple measurements. The ADCs features and benefits are discussed, as is cold junction compensation; this is followed by a lab demonstration of the LTC2492 thermocouple meter. Errata: When the internal temp sensor on the LTC2492 is used, a 2V or higher reference is needed. Please refer to the LTC2492 datasheet for detailed information.
