ADR365WAUJZ-R7

Overview

The ADR365WAUJZ-R7 is a precision 5.000 V band gap voltage reference from Analog Devices, housed in a compact 5-lead TSOT (UJ-5) package. It features an initial accuracy of ±8 mV and a temperature coefficient of 25 ppm/°C over the −40°C to +125°C operating range. The device draws a maximum quiescent current of 190 µA and provides sink/source capability with output currents of −1 mA and +5 mA respectively. It operates with a low dropout voltage of 300 mV and exhibits ultralow output voltage noise of 12.8 µV p-p from 0.1 Hz to 10 Hz. No external capacitors are required for stability.

Feature Summary

• Proprietary temperature drift curvature correction techniques achieve low temperature drift within a compact package.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Micropower operation with low dropout voltage allows stable output from minimal supply headroom.
• Sink/source output capability supports both sourcing up to 5 mA and sinking up to 1 mA.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required grade and packaging format. Confirm the input voltage range aligns with your system's supply rails, as the ADR365 requires a minimum VIN of 5.3 V. Ensure thermal management considerations are addressed for the UJ-5 package if power dissipation limits are approached during high-load conditions.

Selection Notes

Select this component when a precise 5.000 V reference is needed with moderate accuracy requirements (±8 mV). It is suitable for applications where low power consumption is critical but higher noise or drift than B-grade parts is acceptable. Verify that the input voltage can exceed the output by at least 300 mV to maintain regulation under all load conditions.

Part Context

This part belongs to the ADR360/ADR361/ADR363/ADR364/ADR365/ADR366 family of low-power, low-noise voltage references. The family offers various fixed output voltages including 2.048 V, 2.500 V, 3.000 V, 4.096 V, 5.000 V, and 3.300 V. All members share similar architectural benefits such as capacitor-free operation and sink/source drive capabilities in a small TSOT package.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Analog Devices directly for qualified alternatives or cross-reference options based on specific electrical and mechanical constraints.
