General Description

The REF01 and REF02 are precision voltage references

that are pretrimmed to within ±3% of +10V and +5V,

respectively. Both references feature excellent tempera-

ture stability (as low as 8.5 ppm/°C worst case), low cur-

rent drain, and low noise. The REF02 also provides a

TEMP pin whose output voltage varies linearly with tem-

perature, making this device suitable for a wide variety of

temperature-sensing and control applications. Both

devices are available from Maxim in the space-saving SO

package, as well as in the standard 8-pin TO-99 and

MINI-DIP packages.
