Overview
The ADR431BRZ-REEL7 is a precision voltage reference from Analog Devices, featuring an output of 2.5 V and B-grade initial accuracy of ±0.04%. It utilizes XFET technology to achieve low noise (3.5 µV p-p at 0.1 Hz to 10 Hz) and a temperature coefficient of 3 ppm/°C over the -40°C to +125°C range. The device operates with a supply voltage of 4.5 V to 18 V, draws 800 µA quiescent current, and provides 30 mA source and -20 mA sink current in an 8-lead SOIC package.
Feature Summary
- XFET technology minimizes voltage change versus temperature nonlinearity for high stability.
- Capable of sourcing up to 30 mA and sinking up to -20 mA without external components.
- Features a trim terminal allowing output voltage adjustment over a ±0.5% range.
- Requires no external capacitor for operation while maintaining ultralow noise performance.
Applications
- Precision data acquisition systems
- High resolution data converters
- Medical instruments
- Industrial process control systems
Procurement Notes
Verify the specific suffix REEL7 indicates tape and reel packaging when ordering. Confirm that the B grade designation corresponds to the required 3 ppm/°C temperature coefficient and ±0.04% initial accuracy specifications. Ensure the SOIC-8 package type matches the design footprint requirements.
Selection Notes
Select this component for applications requiring low noise and high accuracy in a surface-mount format. The 2.5 V output suits 5 V system architectures. Consider the 4.5 V minimum input requirement and 2 V headroom specification against available supply rails.
Part Context
This part belongs to the ADR43x series of ultralow noise XFET voltage references. It shares core architectural features with models like the ADR430, ADR433, ADR434, and ADR435, differing primarily in nominal output voltage and minimum operating input voltage ranges.
