REF01HSA

19-0887; Rev 7; 4/07 +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: 10µVP-P (REF02) ♦ Short-Circuit Protected ♦ Linear Temperature Transducer Output (REF02) Features REF01/REF02 Ordering Information PART REF01EP REF01EP+ REF01HP REF01HP+ REF01HSA REF01HSA+ REF01CP REF01CP+ REF01CSA REF01CSA+ REF01CESA REF01CESA+ TEMP RANGE 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C -40°C to +85°C -40°C to +85°C MAX TEMPCO (ppm/°C) 8.5 8.5 25 25 25 25 65 65 65 65 65 65 INITIAL ERROR (mV) ±30 ±30 ±50 ±50 ±50 ±50 ±100 ±100 ±100 ±100 ±100 ±100 PIN-PACKAGE 8 Plastic DIP 8 Plastic DIP 8 Plastic DIP 8 Plastic DIP 8 SO 8 SO 8 Plastic DIP 8 Plastic DIP 8 SO 8 SO 8 SO 8 SO PKG CODE P8-2 P8-2 P8-2 P8-2 S8-2 S8-2 P8-2 P8-2 S8-2 S8-2 S8-2 S8-2 +Denotes a lead-free package.

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 _______________________________________________________________________________________ +5V, +10V Precision Voltage References REF01/REF02 ABSOLUTE MAXIMUM RATINGS–REF02 Input Voltage REF02, E, H .........................................................................40V REF02C ...............................................................................30V Continuous Power Dissipation Plastic Dip (P) (derate at 5.6mW/°C above +36°C) .....500mW Small Outline (S) (derate at 5.0mW/°C above +55°C) ..300mW Storage Temperature Range .............................-65°C to +150°C Operating Temperature Range REF02E, REF02H .................................................0°C to +70°C REF02C (except REF02CESA) ............................0°C to +70°C REF02CESA ......................................................-40°C to +85°C Output Short-Circuit Duration (to ground or VIN) .......................................................Indefinite Lead Temperature (soldering, 60s) .................................+300°C Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
