General Description

Features

ꢀ Pretrimmed to +5V, +10V 0ꢀ.3

The REF01 and REF02 are precision voltage references

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

respectively. Both references feature excellent tempera-

ture stability (as low as 8.+ ppm/°C worst case)V low cur-

rent drainV and low noise. The REF02 also provides a

TEMP pin whose output voltage varies linearly with tem-

peratureV 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

packageV as well as in the standard 8-pin TO-99 and

MINI-DIP packages.

Adjustment of the output does not significantly affect

the temperature performance of the device. The tem-

perature coefficient change is approximately

0.7ppm/°C for 100mꢁ of output adjustment.

Output Adjustment

The REF01 trim terminal can be used to adjust the volt-

age over a 10ꢁ±±00mꢁ range. This feature allows the

system designer to trim system errors by setting the ref-

erence to a voltage other than 10ꢁV including 10.240ꢁ

for binary applications (see the Typical Operating

Circuit section).

Output Adjustment

The REF02 trim terminal can be used to adjust the out-

put voltage over a +ꢁ±±00mꢁ range. This feature

allows the system designer to trim system errors by set-

ting the reference to a voltage other than +ꢁ (refer to

the Typical Operating Circuit section).

Adjustment of the output does not significantly affect

the temperature performance of the device. TypicallyV

the temperature coefficient change is 0.7ppm/°C for

100mꢁ 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 temperatureV and has a scale factor of

approximately 2.1mꢁ/°C (Figure 2).

Output ꢁoltage = 2.1(T ꢀ 27±)mꢁ
