+5V, +10V Precision Voltage References
General Description
The REF01/REF02 are industry-standard precision voltage 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. Pretrimmed to +5V, +10V Excellent Temperature Stability: 3ppm/C (typ) Low Noise: 10VP-P (REF02) Short-Circuit Protected Linear Temperature Transducer Output (REF02)

Output Adjustment
The REF01 trim terminal can be used to adjust the voltage over a 10V 600mV range. This feature allows the system designer to trim system errors by setting the reference 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 temperature coefficient change is approximately 0.7ppm/C for 100mV of output adjustment.

Output Adjustment
880 TEMP VOLTAGE OUTPUT (mV)
The REF02 trim terminal can be used to adjust the output voltage over a 5V 300mV range. This feature allows the system designer to trim system errors by setting 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.
