I'm exploring to use MCU's internal ADC (16-bits sigma-delta) for PT100 temperature measurements.
Looking for temperature accuracy of around 0.2degC.
1) Can you share any reference design for PT100 measurements using MCU's internal ADC?
2) Is MSP430 variant available with digital filters for sigma delta modulator (DFSDM)? DFSDM can be used for MCU's internal16-bits sigma-delta ADC?
3) Temperature accuracy of around 0.2degC can be achieved with MCU's internal16-bits sigma-delta ADC (with DFSDM)?
