+2.5 V Low Power Precision  
Voltage Reference  
REF43  
FEATURES  
PIN CONFIGURATION  
GENERAL DESCRIPTION  
Tight output tolerances and low thermal drift are assured by  
zener-zap trimming of both output voltage and its temperature  
coefficient. A unique curvature correction circuit reduces the  
thermal curvature which is characteristic of many previous  
bandgap references.  
The REF43 is a low power precision reference providing a  
stable 2.5 V output independent of variations in supply voltage,  
load conditions or ambient temperature. It is suitable as a  
reference level for 8-, 10- and 12-bit data acquisition systems,  
or wherever a stable, known voltage is required.

CAUTION  
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily  
accumulate on the human body and test equipment and can discharge without detection. Although the  
REF43 features proprietary ESD protection circuitry, permanent damage may occur on devices  
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended  
to avoid performance degradation or loss of functionality.
