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.
