ADR5044ARTZ-REEL7

Overview

The ADR5044ARTZ-REEL7 is a precision shunt voltage reference from Analog Devices, housed in an SOT-23-3 surface-mount package. It provides a nominal output voltage of 4.096 V with an initial accuracy of ±0.2%. The device operates within a wide current range of 50 µA to 15 mA and maintains stability without requiring external compensation capacitors. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Ultracompact SOT-23 package design for space-critical applications
• Low temperature coefficient ensuring stable performance over wide thermal ranges
• Pin-compatible with LM4040/LM4050 for simplified circuit upgrades
• Stable operation with any capacitive load without external compensation

Applications

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

Procurement Notes

Verify the specific suffix ARTZ corresponds to the SOT-23-3 package and REEL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering quantity matches the standard factory pack size of 3000 units if purchasing directly from production lines.

Selection Notes

Select this component when a 4.096 V reference is required in a small footprint. The Grade A specification offers ±0.2% initial accuracy and 100 ppm/°C temperature coefficient. Consider the B-grade variant if tighter tolerance (±0.1%) and lower drift (75 ppm/°C) are needed. Verify that the operating current requirements fall within the 50 µA to 15 mA range for optimal performance.

Part Context

This part belongs to the ADR504x family of micropower shunt mode voltage references. The family includes variants with different output voltages such as 2.048 V, 2.5 V, 3.0 V, and 5.0 V. All members share similar architectural features, including band-gap technology and ultrasmall package options like SC-70 and SOT-23.
