ADR391AUJZ-REEL7

Overview

The ADR391AUJZ-REEL7 is a micropower, low noise precision voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.24% and a temperature coefficient of 25 ppm/°C. The device operates within an input voltage range of 2.8 V to 15 V and supports a maximum load current of 5 mA. It features a shutdown mode that reduces supply current to 3 μA maximum, while normal operation consumes 140 μA maximum. The unit utilizes a TSOT-23-5 surface mount package and functions across a wide temperature range from -40°C to +125°C.

Feature Summary

Patented curvature correction techniques ensure stable output voltage across the full operating temperature range.
Advanced internal design eliminates the need for external capacitors to maintain circuit stability.
Integrated shutdown pin allows for ultra-low power consumption in standby states.

Applications

Battery-powered instrumentation
Portable medical instrumentation
Data acquisition systems
Industrial process controls

Procurement Notes

Verify the specific grade suffix (U) corresponds to the required A-grade specifications during procurement. Confirm the REEL7 packaging designation matches the manufacturing lot requirements. Ensure the ordering part number aligns with the exact voltage and tolerance needs defined in the datasheet electrical characteristics table.

Selection Notes

Select this component when a fixed 2.5 V reference is required with A-grade accuracy. Consider the TSOT-23-5 package constraints for board space limitations. Evaluate the 300 mV dropout voltage against the minimum available supply rail to ensure proper regulation under all load conditions.

Part Context

This component belongs to the ADR39x family of micropower voltage references, which also includes the ADR392 and ADR395 models offering different output voltages. All members share similar architectural features, including low noise performance and shutdown capabilities, but differ in their nominal output levels and specific line regulation parameters.
