Ah, yes, the AD590. Among the specifications, we find:
Long-Term Drift: ±0.1°C/month max
That's roughly 3 millidegrees per day.
And it's one microamp per degree K, about 300 microamps at

Why mess with bridges, etc? Analog Devices, among others, make solid state
temperature sensors that are very good and put out linearized currents,
something like 1 mV / Degree K.
