This application note provides guidelines on Kinetis K53 family for using the internal Operational Amplifiers (OPAMP), Transimpedance Amplifiers (TRIAMP), and the Analog-to-Digital Converter (ADC) modules to measure the temperature through a thermocouple and a thermistor and the result is shown on a LCD display using the LCD Controller (LCD) module. All these modules are available on the K53 MCU.

 

The application uses different OPAMP configurations, such as internal gain and external gain using external resistor. TWR-K53N512 board was used as base hardware for performing this application.

 

 

 

 

Watch the Freescale Kinetis K53 family in action. The internal Operational Amplifiers (OPAMP), Transimpedance Amplifiers (TRIAMP), and the Analog-to-Digital Converter (ADC) modules are used to measure the temperature through a thermocouple and a thermistor. The result is shown on a LCD display using the LCD Controller (LCD).
