GENERAL DESCRIPTION  
NC = NO CONNECT. DO NOT CONNECT ANYTHING  
ON THESE PINS. SOME OF THEM ARE RESERVED  
FOR FACTORY TESTING PURPOSES.  
The REF02 precision voltage reference provides a stable 5 V  
output that can be adjusted over a ±±6 range with minimal  
effect on temperature stability. Single-supply operation over an  
input voltage range of 7 V to 40 V, low current drain of 1 mA,  
and excellent temperature stability are achieved with an  
improved band gap design. Low cost, low noise, and low power  
make the REF02 an excellent choice whenever a stable voltage  
reference is required. Applications include DACs and ADCs,  
portable instrumentation, and digital voltmeters. The versatility  
of the REF02 is enhanced by its use as a monolithic temperature  
transducer. For new designs, refer to ADR02.
