ADR5041ARTZ-REEL

Overview

The ADR5041ARTZ-REEL7 is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 100 ppm/°C. The device operates within a wide current range from 50 µA to 15 mA and functions across an extended temperature range of −40°C to +125°C. It is housed in an ultracompact SOT-23-3 surface-mount package, designed for space-critical applications without requiring external compensation capacitors.

Feature Summary

• Ultracompact SOT-23-3 package design suitable for space-constrained layouts
• High precision performance with low temperature drift characteristics
• Wide operating current range supporting diverse load conditions
• Extended temperature range capability for harsh environments

Applications

• Portable battery-powered equipment
• Automotive systems
• Data acquisition systems
• Instrumentation and process control
• Energy management

Procurement Notes

Verify the specific grade (A or B) and suffix requirements against the official Analog Devices ordering guide. Confirm that the REEL7 designation matches the required tape-and-reel packaging format for automated assembly processes. Ensure compatibility with RoHS compliance standards if applicable to the target market regulations.

Selection Notes

Select this component when a stable 2.5 V reference is needed in a minimal footprint. Consider the ±0.2% initial accuracy and 100 ppm/°C temperature coefficient limits for system precision requirements. Evaluate the 50 µA minimum operating current constraint against the application's quiescent power budget and load variations.

Part Context

This part belongs to the ADR504x family of micropower shunt voltage references, which includes variants with different output voltages such as 2.048 V, 3.0 V, 4.096 V, and 5.0 V. The family shares common features like pin compatibility with LM4040/LM4050 devices and stability with any capacitive load, offering designers a modular solution for various reference voltage needs.

Replacement Considerations

The datasheet explicitly states pin compatibility with LM4040 and LM4050 devices. Designers should verify electrical specifications against these equivalents to ensure functional interchangeability in existing designs.
