Harsh Environment Acquisition Terminal (HEAT) EVM Platform for High Temperature Applications


Design files


The HEATEVM is a MCM intended to provide a high temperature platform for signal conditioning and processor evaluation. The module consists of a complete chain of components designed to withstand extreme operating temperatures up to 200 °C. The PCB is made with polymide material also suited for these extreme temperatures.

  • Qualified high temperature components (200°C)
  • Up to 8 channels of analog data
  • Analog signals conditioned, digitized and processed at temperature
  • One platform to evaluate a large number of high temperature devices
  • This MCM reference design is tested and orderable at ti.com, where firmware, GUI and user's guide and fabrication files are provided

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
