Overview
The ADR5044WBRTZ-R7 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 4.096 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 SOT-23-3 surface-mount package and is qualified for automotive applications.
Feature Summary
- Ultracompact SOT-23 package design suitable for space-critical applications
- High precision performance with low temperature drift characteristics
- Qualified for automotive applications under controlled manufacturing standards
- Operates without requiring external compensation capacitors
Applications
- Portable, battery-powered equipment
- Automotive systems
- Data acquisition systems
- Instrumentation and process control
- Energy management
Procurement Notes
Verify the specific suffix 'W' indicates automotive qualification and 'B' denotes the ±0.1% accuracy grade. Confirm the 'RT' package designation matches the required SOT-23 footprint. Ensure the '-R7' suffix aligns with reel packaging requirements. Cross-reference the manufacturer part number against official datasheets to validate RoHS compliance status before integration into designs.
Selection Notes
Select this component when high accuracy and automotive reliability are required in a small form factor. The 4.096 V output suits ADC/DAC references. Consider the 50 µA minimum operating current for low-power standby modes. Evaluate thermal resistance values if operating near maximum current limits. Verify that the 15 mA maximum shunt current meets load requirements.
Part Context
This device belongs to the ADR504x family of precision shunt voltage references. The family includes variants with different output voltages (2.048 V, 2.5 V, 3.0 V, 5.0 V) and accuracy grades. The 'W' suffix specifically identifies models qualified for automotive use, distinguishing them from standard commercial versions while sharing core electrical characteristics.
