TIPD193, RTD to Voltage Reference Design Using Instrumentation Amplifier and Current Reference

TIPD193, RTD to Voltage Reference Design Using Instrumentation Amplifier and Current Reference. 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
