Temperature Measurement and Readout Using Internal ADC

This 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.

Features

• 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
