General Description

The REF01/REF02 are industry-standard precision volt-

age references. The stable 10V output of the REF01

can be adjusted over a ±6% range with minimal effect

on temperature stability. The 5V output REF02 can also

be adjusted over a ±6% range. The 10V REF01 has a

single-supply operation over an input voltage range of

13V to 33V, while the 5V REF02 has a single-supply

operation over an input voltage range of 7V to 33V.

Both devices offer a low-current drain of 1mA. 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. For new designs, refer to the

MAX6035 or MAX6143 data sheets.
