www..com 19-0887; Rev 3; 6/03 +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 3% range with minimal effect on temperature stability, while the 5V output REF02 can 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, please refer to the MAX6035 or MAX6143 data sheets. o Pretrimmed to +5V, +10V 0.3% o Excellent Temperature Stability: 3ppm/C o Low Noise: 10VP-P (REF02) o Low Supply Current: 1.4mA (max) o Short-Circuit Proof o Linear Temperature Transducer Output (REF02) Features REF01/REF02 Ordering Information www..com 1 PART REF01EP REF01HP REF01HSA REF01CP REF01CSA REF01CESA REF02EP REF02HP REF02HSA REF02CP REF02CSA REF02CESA TEMP RANGE 0C to +70C 0C to +70C 0C to +70C 0C to +70C 0C to +70C -40C to +85C 0C to +70C 0C to +70C 0C to +70C 0C to +70C 0C to +70C -40C to +85C MAX TEMPCO (ppm/C) 8.5 25 25 65 65 65 8.5 25 25 65 65 65 INITIAL ERROR (mV) 30 50 50 100 100 100 15 25 25 50 50 50 PIN-PACKAGE 8 Plastic DIP 8 Plastic DIP 8 SO 8 Plastic DIP 8 SO 8 SO 8 Plastic DIP 8 Plastic DIP 8 SO 8 Plastic DIP 8 SO 8 SO Ordering Information continued at end of data sheet.

Note 5: TCVO is defined as VOT divided by the temperature range. Output Adjustment The REF01 trim terminal can be used to adjust the voltage over a 10V 300mV 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. _______________________________________________________________________________________ 3 www..com www..com www..com 4U DataSheet 4 U .com www..com REF01/REF02 www..com +5V, +10V Precision Voltage References REF01/REF02 ABSOLUTE MAXIMUM RATINGS-REF02 Input Voltage REF02, A, E, H, All DICE .....................................................40V REF02C, D...........................................................................30V Continuous Power Dissipation T099 (J) (derate at 7.1mWC above +80C).................500mW CERDIP (2) (derate at 6.7mW/C above +75C) .........500mW Plastic Dip (P) (derate at 5.6mW/C above +36C) .....500mW Small Outline (S) (derate at 5.0mW/C above +55C) ..300mW Storage Temperature Range .............................-65C to +150C Operating Temperature Range REF02A, REF02 ..............................................-55C to +125C REF02E, REF02H (except REF02CESA)..............0C to +70C REF02C (except REF02CESA), REF02D .............0C to +70C REF02CESA ......................................................-40C to +85C Lead Temperature (soldering, 60s) .................................+300C DICE Junction Temperature (Tj) ........................-65C to +150C Output Short-Circuit Duration (to ground or VIN) .......................................................Indefinite Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

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. Figure 1.
