ADR5040ARTZ-REEL

Overview

The ADR5040ARTZ-REEL is a precision micropower shunt mode voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.048 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. Housed in an ultracompact SOT-23-3 surface-mount package, it requires no external compensation capacitor for stability.

Feature Summary

• Ultracompact packaging designed for space-critical applications
• High precision with low temperature drift characteristics
• Wide operating current range suitable for battery-powered equipment
• Stable operation without the need for external capacitors

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 2.048 V output and ±0.2% initial accuracy. Confirm the SOT-23-3 package type and REEL7 tape-and-reel packaging format align with manufacturing requirements. Ensure compliance with RoHS standards and check for any automotive qualification suffixes if applicable to the target environment.

Selection Notes

Select this component when a stable, low-drift voltage reference is needed in a small footprint. The wide operating current range allows flexibility in bias resistor selection for varying supply voltages. Consider the ±0.2% accuracy grade for general precision applications where tighter tolerances are not strictly required. Evaluate thermal management needs based on the maximum shunt current rating.

Part Context

This device belongs to the ADR504x family of precision micropower shunt voltage references, which includes variants with different output voltages such as 2.5 V, 3.0 V, 4.096 V, and 5.0 V. The family shares common features like ultracompact packaging and high accuracy. The ARTZ suffix indicates the SOT-23-3 package option, while other options include SC70 packages.

Replacement Considerations

The datasheet notes pin compatibility with LM4040/LM4050 devices. Designers should verify electrical specifications against these alternatives to ensure functional equivalence in terms of voltage, accuracy, and temperature coefficient.
