ADR361BUJZ-R2

Overview

The ADR361BUJZ-R2 is a precision band gap voltage reference providing a nominal output of 2.500 V. It operates within an input voltage range of 2.8 V to 15 V and delivers a maximum quiescent current of 190 µA across the -40°C to +125°C temperature range. The device features B-grade initial accuracy of ±3 mV maximum and a temperature coefficient of 9 ppm/°C. It supports sourcing up to 5 mA and sinking up to 1 mA, with a low dropout voltage of 300 mV. Output noise is specified at 8.25 µV p-p from 0.1 Hz to 10 Hz.

Feature Summary

• Utilizes proprietary temperature drift curvature correction techniques for high precision in compact TSOT packages.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Provides stable output voltage with a minimum supply headroom of only 300 mV above the output.
• Capable of sourcing +5 mA and sinking -1 mA load currents without requiring external components.

Applications

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

Procurement Notes

Verify that the specific ordering suffix corresponds to the required reel packaging configuration. Confirm the grade designation matches the necessary accuracy and temperature coefficient specifications for the target application environment. Ensure compatibility with the intended PCB footprint and soldering thermal profiles.

Selection Notes

Select this component when a fixed 2.5 V reference is required with minimal power consumption and small physical dimensions. Consider the B-grade specifications if tighter tolerance and lower drift are critical compared to the A-grade alternative. Evaluate the input voltage requirements against the 300 mV dropout characteristic to ensure proper regulation under varying load conditions.

Part Context

This part belongs to the ADR36x family of micropower, low dropout voltage references developed by Analog Devices. The family includes variants with different fixed output voltages such as 2.048 V, 3.0 V, and 5.0 V. All members share the same core architecture featuring ultralow noise and high precision in a 5-lead TSOT package.
