Oscillator Circuits for RTD Temperature Sensors
Ezana Haile and Jim Lepkowski
This application note shows how to design a temperature sensor oscillator circuit using Microchip's low-cost MCP6001 operational amplifier (op amp) and the MCP6541 comparator. Oscillator circuits can be used to provide an accurate temperature measurement with a Resistive Temperature Detector (RTD) sensor. Oscillators provide a frequency output that is proportional to temperature and are easily integrated into a microcontroller system.
