GENERAL DESCRIPTION
The ADR390/ADR391/ADR392/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
patented temperature drift curvature correction techniques
from Analog Devices, Inc., 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.
