MAX TEMPCO (ppm/ C) INITIAL ERROR (mv)

19-0887; Rev 7; /07 General Description The are industry-standard precision voltage references. The stable 10V output of the REF01 can be adjusted over a ±% range with minimal effect on temperature stability. The V output REF0 can also be adjusted over a ±% range. The 10V REF01 has a single-supply operation over an input voltage range of 13V to 33V, while the V REF0 has a single-supply operation over an input voltage range of 7V to 33V. Both devices offer a low-current drain of 1mA. The REF0 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 MAX03 or MAX13 data sheets. +V, +10V Precision Features Pretrimmed to +V, +10V Excellent Temperature Stability: 3ppm/ C (typ) Low Noise: 10µV P-P (REF0) Short-Circuit Protected Linear Temperature Transducer Output (REF0) Ordering Information PART TEMP RANGE MAX TEMPCO (ppm/ C) INITIAL ERROR (mv) PIN-PACKAGE REF01EP 0 C to +70 C 8. ±30 8 Plastic DIP P8- REF01EP+ 0 C to +70 C 8. ±30 8 Plastic DIP P8- REF01HP 0 C to +70 C ±0 8 Plastic DIP P8- REF01HP+ 0 C to +70 C ±0 8 Plastic DIP P8- REF01HSA 0 C to +70 C ±0 8 SO S8- REF01HSA+ 0 C to +70 C ±0 8 SO S8- REF01CP 0 C to +70 C ±100 8 Plastic DIP P8- REF01CP+ 0 C to +70 C ±100 8 Plastic DIP P8- REF01CSA 0 C to +70 C ±100 8 SO S8- REF01CSA+ 0 C to +70 C ±100 8 SO S8- REF01CESA -0 C to +8 C ±100 8 SO S8- REF01CESA+ -0 C to +8 C ±100 8 SO S8- +Denotes a lead-free package.

Output Adjustment The REF01 trim terminal can be used to adjust the voltage over a 10V ±00mV range. This feature allows the system designer to trim system errors by setting the reference to a voltage other than 10V, including 10.0V 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. 3

Note : Line and load regulation specifications include the effect of self heating. 100% production tested at T A = + C and guaranteed by design for T A = T MIN to T MAX, as specified. Note 7: Limit current in or out of pin 3 to 0nA and capacitance on pin 3 to 30pF. Note 8: T is defined as the absolute difference between the maximum output voltage and the minimum output voltage over the specified temperature range expressed as a percentage of V. Guaranteed by design. T = VMAX -VMIN V 100 Note 9: TC is defined as T divided by the temperature range. Guaranteed by design. Output Adjustment The REF0 trim terminal can be used to adjust the output voltage over a V ±300mV range. This feature allows the system designer to trim system errors by setting the reference to a voltage other than V (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 REF0 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.1mv/ C (Figure 1). Output Voltage =.1(T + 73)mV where T = Temperature in C.
