ADR360AUJZ-R2

Overview

The ADR360AUJZ-R2 is a micropower, low noise series voltage reference from Analog Devices Inc., housed in a compact TSOT-23-5 package. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.29% and a temperature coefficient of 25 ppm/°C. The device operates within a supply voltage range of 2.35 V to 15 V, drawing a maximum quiescent current of 190 µA. It supports sourcing up to 5 mA and sinking up to 1 mA, featuring ultralow output voltage noise of 6.8 µV p-p (0.1 Hz to 10 Hz) and a dropout voltage of 300 mV.

Feature Summary

• Proprietary temperature drift curvature correction techniques enable high precision in a small footprint without external capacitors.
• Advanced band gap architecture references the output rather than ground, significantly attenuating noise present on the ground line.
• Capable of both sourcing and sinking load currents, providing flexibility for various circuit configurations.

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeits. Confirm the specific grade (A or B) matches design requirements, as performance varies. Check for automotive qualification if operating in harsh environments. Ensure input voltage headroom meets the 300 mV dropout specification under all load conditions.

Selection Notes

Select this part when low power consumption and high precision are critical in space-constrained designs. The A grade offers standard precision, while the B grade provides tighter accuracy. Consider the thermal resistance characteristics for PCB layout to manage power dissipation effectively at higher input voltages.

Part Context

This component belongs to the ADR36x family of low power, low noise voltage references. It shares architectural similarities with the ADR361, ADR363, ADR364, ADR365, and ADR366 models, differing primarily in output voltage and specific grading. All members utilize the same TSOT-23-5 package and offer sink/source capability.

Replacement Considerations

Direct substitutes include other parts within the ADR36x family such as the ADR361AUJZ-R2 or ADR363AUJZ-R2, provided the output voltage difference is acceptable. Verify pin compatibility and thermal characteristics before substitution.
