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 temper-

ature stability (as low as 8.5ppm/°C worst case), low

current drain, and low noise. The REF02 also provides

a TEMP pin whose output voltage varies linearly with

temperature, 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.
