Design files

Overview

The TIDA-060042 reference design demonstrates a fully space-graded ratiometric temperature sensing circuit using ADS1282EVM-PDK. This circuit measures temperature at up to 10 different locations without any use of buffers. The majority of space applications require temperature measurement in multiple subsystems that will benefit from this multilocation circuit.

Features
  • Measure temperature at up to 10 different locations
  • Ratiometric temperature sensing
  • 99.93% accuracy
  • No use of buffer
  • Small size
