Design Considerations

Complete Temperature Sensing and Control Solution

  • 2-, 3-, 4-wire RTDs
  • RTD 4-wire to 3-wire auto reconfiguration for high reliability
  • All thermocouple types (J, K...)
  • Thermistors
  • Voltage output temperature sensors
  • Diodes used as temperature sensors
  • Digital sensors (I2C, SPI, TMP05)
  • Fan control and voltage output

Increase Integration

  • 8- to 20-bit ADC with PGA
  • ±0.003% signal accuracy (non-linearity)
  • 0.1% internal voltage reference
  • Up to four unique programmable voltage or current sources
  • Supports multiple channels (e.g., ten 4-wire RTD sensors)
  • Control output (i.e. fan or voltage output)
  • Linearization algorithm or lookup table

Reduced Design Time

  • CY8CKIT-025 evaluation board with multiple sensors included to jump-start the design
  • Detailed sensor interface design guidelines in app notes with example projects
  • PSoC Creator’s schematic and component-based approach simplifies solution design
