Hello! I want to interface PT500/1000 Sensor with 24-bit AD7714. Please tell me how to do the circuit designing to have a stable accuracy of 0.0001 degree Celsius. Is this accuracy achievable with AD7714? What current source i should prefer? What should be my OP-AMP Gain? Any other external components required? Reply as soon as possible.
