Overview
The ADR4550BRZ-R7 is a high precision, low power voltage reference from Analog Devices featuring a fixed 5.0 V output. It operates within an extended industrial temperature range of -40°C to +125°C and utilizes an innovative core topology for excellent stability. The device offers a maximum initial accuracy of ±0.02% and a temperature coefficient of 2 ppm/°C. It supports up to 10 mA sourcing and sinking current with a maximum quiescent current of 950 μA.
Feature Summary
- Ultra-low noise performance suitable for sensitive analog circuits
- High accuracy with minimal initial error and temperature drift
- Low dropout voltage capability for efficient power management
- Robust long-term stability over time and thermal variations
Applications
- Precision data acquisition systems
- High resolution data converters
- Industrial instrumentation

Procurement Notes
Verify the specific B-grade designation and SOIC-8 package configuration against project requirements. Confirm that the operating environment falls within the specified -40°C to +125°C range. Ensure input voltage constraints between 5.1 V and 15 V are met during system design validation.
Selection Notes
Select this component when a stable 5.0 V reference is required in space-constrained designs. The B-grade specification ensures suitability for harsh industrial environments. Consider the low quiescent current for battery-operated applications requiring extended operational life without compromising precision.
Part Context
This part belongs to the ADR45xx series of ultralow noise voltage references. It shares architectural similarities with other members like the ADR4533 and ADR4540 but provides a distinct 5.0 V output level. The family is designed to replace older generation references while offering improved noise and drift characteristics.
