Low-cost YSI44018 temperature sensor in feedback loop of 741J opamp gives accuracy approaching that of platinum sensors. Opamp is driven by AD58O band-gap refelence. Voltage output of A1 feeds similar opamp that provides zeroing and sets desired output gain.-J. Williams, Designer's Guide to： Temperature Measurement,EDN Magazine,May 20,1977,p71-77.
