ADR390BUJZ-R2

精密，低漂移2.048 V / 2.5 V / 4.096 V / 5.0 V SOT- 23参考与关机 Precision Low Drift 2.048 V/2.5 V/4.096 V/ 5.0 V SOT-23 Reference with Shutdown

**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 ’s patented temperature drift curvature correction techniques, the ADR39x references achieve a low 9 ppm/°C of temperature drift in the TSOT package.
