GENERAL DESCRIPTION
The 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.
