They are a current source, where current is proportional to absolute temperature. Room temperature (20 C) is 293 uA. You can read this with a DVM and a 9 V battery. I have a signal conditioning board and feed this to a very old-school multiplexed ADC. it used to be hooked to my VAX, but now that the VAX is retired, it is connected to my one of my Linux machines.
