ADR290GR-REEL7

Overview

The ADR290GR-REEL7 is a precision voltage reference IC from Analog Devices, providing a stable fixed output of 2.048V. It operates within an input voltage range up to 15V and supports a maximum shunt current of 5mA. The device features low noise characteristics and micropower consumption with a typical operating supply current of 12uA. Initial accuracy is specified at 0.08%, with a temperature coefficient of 3 PPM/C. It functions reliably across a wide temperature range from -40°C to +125°C. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Delivers a precise 2.048V fixed output for accurate signal conditioning
• Optimized for low power applications with minimal quiescent current draw
• Maintains high stability over extended industrial temperature ranges

Applications

• Power management systems requiring stable reference voltages
• Precision data acquisition circuits
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix GR against official Analog Devices documentation to confirm the exact accuracy grade and packaging configuration. Ensure compatibility with your PCB footprint and thermal requirements. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference the datasheet revision date to ensure all electrical specifications align with your design constraints before finalizing procurement.

Selection Notes

Select this component when a fixed 2.048V reference is required with high initial accuracy and low temperature drift. Consider the SOIC-8 package for surface-mount assembly needs. Evaluate the 12uA supply current against battery life requirements for portable devices. Ensure the input voltage does not exceed the maximum rating while supporting the necessary load current within the 5mA limit.

Part Context

This part belongs to the ADR290 series of low noise micropower precision voltage references. It shares architectural similarities with other members like the ADR291 and ADR292, differing primarily in output voltage and accuracy grades. The series is designed for applications demanding high stability and low power consumption in compact packages.

Replacement Considerations

Direct substitutes include other ADR290 variants such as ADR290ER or ADR290FR, which offer different accuracy grades but share the same pinout and functionality. Verify that alternative parts meet the specific 0.08% accuracy requirement if replacing with non-GR suffixes.
