ADR380ART-R2

Overview

The ADR380ART-R2 is a micropower, low dropout voltage reference providing a nominal output of 2.048 V in a 3-lead SOT-23 package. It features an initial accuracy error of ±5 mV and a maximum temperature coefficient of 25 ppm/°C over the -40°C to +85°C range. The device operates with a supply voltage from 2.4 V to 18 V, drawing a quiescent current of 120 μA maximum. It delivers up to 5 mA output current with a minimum headroom of 300 mV.

Feature Summary

• Patented temperature drift curvature correction techniques minimize nonlinearity of voltage change with temperature.
• Micropower architecture designed for battery-powered applications with wide operating ranges.
• Low dropout voltage design allows stable operation with minimal supply overhead.

Applications

• Battery-powered instrumentation
• Portable medical instruments
• Data acquisition systems
• Industrial process control systems

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm packaging quantity and RoHS compliance status. Confirm that the RT-3 package option matches the required footprint. Ensure the component meets the specified industrial temperature range requirements for the target application environment before finalizing procurement.

Selection Notes

Select this component when a precise 2.048 V reference is needed in a compact surface-mount form factor. Consider the 120 μA quiescent current limit for power-sensitive designs. Evaluate the 5 mA load capability against system requirements. Verify compatibility with the 2.4 V to 18 V input voltage range.

Part Context

This part belongs to the ADR38x series of precision band gap voltage references manufactured by Analog Devices. It shares architectural similarities with the ADR381 but provides a fixed 2.048 V output instead of 2.500 V. The series utilizes patented curvature correction for enhanced stability across temperature variations.
