ADR5045ARTZ-REEL7

Voltage Reference Overview

The ADR5045ARTZ-REEL7 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5.0 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 reliably 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.

Voltage Reference Feature Summary

• Ultracompact SOT-23-3 package design suitable for space-critical applications
• High precision performance with low temperature drift characteristics
• Wide operating current range supporting both micropower and higher load conditions
• Extended temperature range operation for harsh environments

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific grade suffix (A or B) against project requirements, as the ADR5045ARTZ-REEL7 designation corresponds to Grade A specifications. Confirm RoHS compliance status via official documentation before integration. Ensure the ordering quantity matches the reel packaging format specified in the manufacturer's ordering guide to avoid supply discrepancies.

Voltage Reference Selection Notes

Select this component when a stable 5.0 V reference is required in a minimal footprint. The Grade A specification offers standard precision suitable for general data acquisition. Consider the Grade B variant if tighter accuracy and lower temperature coefficients are necessary. Verify that the system bias resistor allows current flow within the 50 µA to 15 mA operational window.

Voltage Reference Part Context

This part belongs to the ADR504x family of precision shunt voltage references, which includes variants with different output voltages such as 2.048 V, 2.5 V, 3.0 V, and 4.096 V. The family shares common features like pin compatibility with LM4040/LM4050 devices and automotive qualification options. The ARTZ suffix indicates the SOT-23-3 package type, while REEL7 denotes the specific tape and reel packaging configuration.

Voltage Reference Replacement Considerations

The datasheet explicitly states pin compatibility with LM4040 and LM4050 devices. Designers should verify electrical parameters match their specific application needs when substituting these parts. No other direct substitute part numbers are confirmed in the provided documentation.
