ADR5041BRTZ-R2

Overview

The ADR5041BRTZ-R2 is a precision micropower shunt mode voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 75 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 3-lead SOT-23 package (RT-3) suitable for surface-mount installation.

Feature Summary

• Ultracompact 3-lead SOT-23 package designed for space-critical applications
• High initial accuracy of ±0.1% with low temperature drift
• Wide operating current range supporting micro-power designs
• Stable with any capacitive load without requiring external compensation

Applications

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

Procurement Notes

Verify the specific suffix RTZ indicates the SOT-23-3 package configuration and REEL7 denotes tape-and-reel packaging. Confirm RoHS compliance status through official documentation. Ensure the ordering quantity matches the standard reel size specified in the manufacturer's guide. Cross-reference the marking code R2Q for identification purposes during assembly.

Selection Notes

Select this component when a stable 2.5 V reference is required in minimal board space. The ±0.1% accuracy grade is suitable for high-precision data acquisition. Consider the 75 ppm/°C temperature coefficient for environments with significant thermal variations. The wide input current range allows flexibility in bias resistor selection for varying supply conditions.

Part Context

This part belongs to the ADR504x family of precision micropower shunt voltage references, which includes variants with outputs of 2.048 V, 3.0 V, 4.096 V, and 5.0 V. The family shares common features such as pin compatibility with LM4040/LM4050 devices and qualification for automotive applications in specific W-series models. The B-grade designation signifies tighter performance tolerances compared to the A-grade counterparts.

Replacement Considerations

Pin-compatible alternatives include the LM4040 and LM4050 series. Other Analog Devices options within the same family are ADR5040B, ADR5043B, ADR5044B, and ADR5045B for different voltage requirements.
