ADR381ARTZ 参考电压 IC

ADR381ARTZ

参考电压 2.048V & 2.5V Bandgap

Precision Low Drift 2.048 V/2.500 V  SOT-23 Voltage Reference

GENERAL DESCRIPTION ADR381ARTZ

The ADR380 and ADR381 are precision 2.048 V and 2.500 V band gap voltage references featuring high accuracy, high stability, and low power consumption in a tiny footprint. Patented temperature drift curvature correction techniques minimize nonlinearity of the voltage change with temperature. The wide operating range and low power consumption make them ideal for 3 V to 5 V battery-powered applications.
