Overview
The ADR290GR is a low noise, micro-power precision voltage reference from Analog Devices utilizing XFET architecture. It provides a fixed output of 2.048 V with an initial accuracy of ±0.29%. The device operates within a supply voltage range up to 15 V and consumes only 12 µA of quiescent current. It features a temperature coefficient of 8 ppm/°C and functions reliably across an extended industrial temperature range from -40°C to +125°C. Packaged in an 8-lead SOIC surface-mount case.
Feature Summary
- Utilizes proprietary XFET architecture for superior stability and low noise performance
- Delivers high precision with tight initial accuracy tolerances
- Designed for ultra-low power consumption suitable for battery-operated systems
Applications
- Portable instrumentation requiring stable reference voltages
- Battery-powered measurement devices
- Data acquisition systems
Procurement Notes
Verify the specific suffix GR indicates the reel packaging format when sourcing. Confirm that the component meets RoHS compliance requirements for your region. Ensure the selected variant matches the required operating temperature range and package type for your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a fixed 2.048 V reference is required with minimal power draw. Consider the 8-lead SOIC package for surface mount assembly needs. Evaluate the 8 ppm/°C drift against system thermal variations to ensure long-term measurement accuracy without external calibration.
Part Context
This part belongs to the ADR29x series of precision voltage references manufactured by Analog Devices. The series includes variants with different output voltages such as 2.5 V and 4.096 V. All members share the same XFET technology base, offering consistent low-noise characteristics and micro-power operation across the product family.
Replacement Considerations
Check for direct equivalents within the ADR29x family if different output voltages are acceptable. Verify pin compatibility with other XFET-based references from Analog Devices or competitors offering similar 2.048 V outputs in SOIC-8 packages.
