ADC Temperature Measurement Readout

Our system is going under maintenance on August 13th between 2:00 pm to 10:00 pm Pacific. During this window, the website may not be reachable. For immediate assistance, please contact

Reference Design LogoThis reference design demonstrates the input of ambient temperature using an input voltage developed using an external resistor/thermistor arrangement. It also shows how to interface to the on-chip ADC and its output registers using I2C commands. Finally, ADC input signal requirements such as scaling and input conditioning are discussed.

This reference design is compatible with the Platform Manager Development Kit.


  • Monitor an external input signal using the on-chip ADC
  • Interfacing requirements to readout the ADC using the I2C interface
  • Demonstrate proper analog signal management requirements
