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.
