ADR5041ARTZ-R2

Overview

The ADR5041ARTZ-R2 is a precision micropower shunt mode 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 optimized for space-constrained environments
• High precision performance with low temperature drift characteristics
• Wide operating current range supporting both micro-power and higher load demands
• Stable operation with any capacitive load without external compensation

Applications

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

Procurement Notes

Verify the specific grade suffix (e.g., ARTZ) against the ordering guide to confirm the exact accuracy and temperature coefficient specifications required for the application. Ensure the packaging format matches the reel quantity specified in the manufacturer's documentation. Confirm RoHS compliance status if environmental regulations apply to the end product assembly.

Selection Notes

Select this component when a stable 2.5 V reference is needed in a small footprint. The Grade A specification offers ±0.2% accuracy and 100 ppm/°C drift. Consider stacking multiple units or using adjustable configurations if different voltage levels are required. Ensure the bias resistor calculation accounts for the minimum 50 µA operating current and maximum 15 mA limit across the full temperature range.

Part Context

This part belongs to the ADR504x family of precision micropower shunt voltage references, which includes variants with outputs of 2.048 V, 3.0 V, 4.096 V, and 5.0 V. The family shares similar architectural features, including pin compatibility with LM4040/LM4050 devices and qualification for automotive applications in specific W-series models. All members utilize band gap technology for stability.

Replacement Considerations

The datasheet explicitly states pin compatibility with LM4040 and LM4050 devices. Designers should verify electrical parameters such as noise and dynamic impedance when substituting these alternatives, as they may differ from the ADR5041 specifications.
