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.

Output Adjustment
The REF01 trim terminal can be used to adjust the volt-
age over a 10V ±600mV range. This feature allows the
system designer to trim system errors by setting the ref-
erence to a voltage other than 10V, including 10.240V for
binary applications (see the Typical Operating Circuit).
Adjustment of the output does not significantly affect the
temperature performance of the device. The tempera-
ture coefficient change is approximately 0.7ppm/°C for
100mV of output adjustment.
