GENERAL DESCRIPTION  
The ADR390, ADR391, ADR392, and ADR395 are precision  
2.048 V, 2.5 V, 4.096 V, and 5 V band gap voltage references,  
respectively, featuring low power and high precision in a tiny  
footprint. Using ADI’s patented temperature drift curvature  
correction techniques, the ADR39x references achieve a low  
9 ppm/°C of temperature drift in the TSOT package.  
The ADR39x family of micropower, low dropout voltage  
references provides a stable output voltage from a minimum  
supply of 300 mV above the output. Their advanced design  
eliminates the need for external capacitors, which further  
reduces board space and system cost. The combination of  
low power operation, small size, and ease of use makes the  
ADR39x precision voltage references ideally suited for battery-  
operated applications.
