GENERAL DESCRIPTION  
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 D/A and A/D converters,  
portable instrumentation, and digital voltmeters. The versatility  
of the REF02 is enhanced by its use as a monolithic temperature  
transducer. For new designs, please refer to ADR02.
