This reference design translates resistance temperature detectors (RTD) resistance to a voltage level convenient for an ADC input. A precision current reference provides excitation and an instrumentation amplifier scales the signal. The design also uses a three wire RTD configuration to minimize errors due to wiring resistance.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
