HEATEVM Evaluation Module



Harsh Environment Acquisition Terminal (H.E.A.T.) evaluation module platform for
high-temperature applications, from Texas Instruments

Texas Instruments HEATEVM Evaluation Module Texas Instruments' H.E.A.T. evaluation module is a high-temperature signal conditioning and processor evaluation platform with a complete signal chain of components designed to withstand extreme operating temperatures up to 210°C. The H.E.A.T. EVM PCB is made with Polyimide material and is suited to withstand temperatures up to 235°C and includes high temperature rated passive components, and utilizes high temperature solder material which makes it well suited for operation in a 200°C operating environment. The H.E.A.T. EVM kit includes the H.E.A.T. board, a low temperature sensor board, cabling, and RS485 communications software. The EVM enables customers to develop applications that can operate in a high-temperature environment quickly with qualified components, risk-free without having to screen off-the-shelve devices for temperature ranges outside their datasheet specifications.
