ADR5045ARTZ-REEL

Voltage Reference Overview

The ADR5045ARTZ-REEL is a precision micropower shunt mode 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 across an extended temperature range of −40°C to +125°C. It is housed in an SOT-23-3 surface-mount package.

Voltage Reference Feature Summary

• Ultracompact packaging suitable for space-critical applications
• Low temperature coefficient for stable performance over temperature variations
• Pin compatible with LM4040/LM4050 devices
• No external capacitor required for stability

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'ARTZ' corresponds to the SOT-23-3 package and Grade A specifications (±0.2% accuracy, 100 ppm/°C TC). Confirm that the REEL designation matches the required tape and reel quantity of 3,000 units. Ensure RoHS compliance status is validated against the latest manufacturer documentation before procurement.

Voltage Reference Selection Notes

Select this component when a 5.0 V shunt reference is required in an SOT-23-3 footprint. It is appropriate for designs needing ±0.2% initial accuracy and operation up to 15 mA shunt current. Consider stacking multiple units if higher voltages are needed, noting that errors accumulate. Verify bias resistor calculations to maintain current between 50 µA and 15 mA under all supply conditions.

Voltage Reference Part Context

This part belongs to the ADR504x family of precision micropower shunt voltage references, which includes variants with outputs of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V. The family shares common features such as low temperature drift and ease of use without external compensation capacitors. The ARTZ suffix specifically denotes the SOT-23-3 package option within this series.

Voltage Reference Replacement Considerations

LM4040 and LM4050 are pin-compatible alternatives.
