This circuit is found in a 2011 technical publication from Texas Instruments. It is an amplifier for RTD temperature sensor with precision that depends on the resistors used. The power supply to the operational amplifier must be symmetrical. The circuit is designed to measure temperatures ranging from 0 ° to 200 ° C. The salts are 0 V at a temperature of 0 ° C and 5 V at 200 ° C.
