3.1 Hardware Requirements

The following three pieces of hardware needed to evaluate the accuracy of the series RTDs temperature sensing system:

  • TIDA-060042: the RTD board that connects 10 RTDs in series and outputs differential RTD voltages as well as the reference voltage. Figure 3-1 shows the schematic of TIDA-060042.

  • ADS1282EVM-PDK: the ADS1282-SP evaluation module. Modification is needed on the evaluation module such that Analog Front End (AFE) is bypass and Vref is directly provided by TIDA-060042.
  • PHI Controller board: this board comes with ADS1282EVM-PDK. The board provides a convenient communication interface to ADS1282EVM-PDK over a USB 2.0 (or higher) for power delivery as well as digital input and output

Figure 3-2 shows an image with all three pieces of hardware connected.
