ADR5040ARTZ-REEL7

Overview

The ADR5040ARTZ-REEL7 is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 2.048 V with an initial accuracy of ±0.2% and a 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 circuitry
• High precision band gap architecture ensuring stable low temperature drift performance
• Wide operating current range supporting both micro-power and higher load requirements
• Stable operation with any capacitive load without the need for external compensation

Applications

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

Procurement Notes

Verify the specific grade suffix (e.g., ARTZ) against the required accuracy and temperature coefficient specifications before procurement. Confirm that the SOT-23-3 package dimensions align with the target PCB footprint. Ensure the ordering quantity matches the standard reel size if bulk purchasing is intended. Cross-reference the RoHS compliance status with local regulatory requirements for the destination market.

Selection Notes

Select this component when a fixed 2.048 V reference is required in a minimal footprint. Consider the Grade A specifications regarding initial accuracy and temperature coefficient relative to system tolerance needs. Evaluate the minimum operating current constraints against the available supply voltage and bias resistor values. Verify thermal resistance characteristics if high ambient temperatures are expected in the application environment.

Part Context

This part belongs to the ADR504x family of 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 architectural features including pin compatibility with LM4040/LM4050 devices and availability in SC70 packages. The ADR5040ARTZ-REEL7 specifically denotes the 2.048 V output version in the SOT-23-3 package configuration.

Replacement Considerations

Pin-compatible alternatives include the LM4040 series. Other ADR504x family members offer different voltage outputs but share similar electrical characteristics and packaging options.
