ce AD580, AD590 integrated temperature sensor and precision instrumentation amplifier AD524 constitution, AD590 compensate for the cold junction, when the cold junction temperature changes, AD590 to lVA/K output current, the current in AD524 foot forming a voltage amplifier and the output is changed vI stack. AD580 provides 2.SV reference voltage. AD524 low-drift (drift voltage 0.5mV, maximum drift 25 mV/oC), good linearity (a gain of l, linearity 0,003%) of high-speed (output slew rate of 5V/ms) operational amplifier.
