ADR5041ARTZ-REEL7

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.

Feature Summary

• Designed for space-critical applications utilizing ultracompact SC70 and SOT-23 packages.
• Eliminates the need for external compensation capacitors while remaining stable with any capacitive load.
• Features low temperature drift and fast settling time for high-precision data acquisition systems.

Applications

• Portable, battery-powered equipment
• Automotives
• Power supplies
• Data acquisition systems
• Instrumentation and process control

Procurement Notes

Verify that the specific part number matches the required Grade A specifications, including the 2.5 V output and ±0.2% initial accuracy. Confirm the SOT-23-3 package type aligns with the PCB footprint requirements. Ensure the operating environment falls within the specified -40°C to +125°C temperature range for optimal performance.

Selection Notes

Select this component when a precise, low-drift voltage reference is needed in a small form factor. The wide operating current range supports both low-power handheld devices and higher-current applications. Verify that the bias resistor calculation accommodates the minimum 50 µA operating current and the maximum 15 mA limit under all supply voltage conditions.

Part Context

This device belongs to the ADR504x family of micropower shunt mode voltage references. The family includes variants with different output voltages (2.048 V, 3.0 V, 4.096 V, 5.0 V) and accuracies. The ARTZ suffix indicates the SOT-23-3 package and RoHS compliance, distinguishing it from the KS-SC70 package variant.

Replacement Considerations

The datasheet notes pin compatibility with LM4040/LM4050 series references. Designers should verify electrical parameters such as temperature coefficient and noise against these alternatives before substitution.

FAQ

Does the ADR5041 require an external capacitor for stability?

No, the advanced design eliminates the need for an external capacitor between the positive and negative terminals, though it remains stable with any capacitive load.

What is the minimum operating current for this reference?

The minimum operating current is 50 µA at 25°C and increases to 60 µA across the extended temperature range of -40°C to +125°C.
