REF01AZ - Maxim Integrated Products, Inc.

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 tempera-

ture stability (as low as 8.5 ppm/°C worst case), low cur-

rent drain, and low noise. The REF02 also provides a

TEMP pin whose output voltage varies linearly with tem-

perature, 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.

ABSOLUTE MAXIMUM RATINGS—REF01

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS—REF01

(VIN = +15V, -55°C ≤ TA= +125°C for REF01A and REF01, 0°C ≤TA≤+70°C for REF01E and REF01H, IL= 0mA, unless otherwise noted.)

Output Adjustment

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

age over a 10V±300mV 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 section).

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 100mV of output adjustment.

ELECTRICAL CHARACTERISTICS—REF02

(VIN = +15V, TA= +25°C, unless otherwise noted.)

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 section).

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 2).

Output Voltage = 2.1(T + 273)mV

where T = Temperature in °C
