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.

Output Adjustment
The REF02 trim terminal can be used to adjust the out-
put voltage over a 5V ±300mV range. This feature
allows the system designer to trim system errors by set-
ting the reference to a voltage other than 5V (refer to
the Typical Operating Circuit).
Adjustment of the output does not significantly affect
the temperature performance of the device. Typically,
the temperature coefficient change is 0.7ppm/°C for
100mV of output adjustment.
Temperature Voltage Output
The REF02 provides a temperature-dependent output
voltage on the TEMP pin. This voltage is proportional to
the absolute temperature, and has a scale factor of
approximately 2.1mV/°C (Figure 1).
Output Voltage = 2.1(T + 273)mV
where T = Temperature in °C.
