REF5020AIDR

Overview

The REF5020AIDR is a fixed series voltage reference IC from Texas Instruments, offering a nominal output of 2.048V with an initial accuracy of ±0.1%. It operates within an input voltage range of 2.7V to 18V and draws a supply current of 1.2mA. The device features a low temperature coefficient of 8ppm/°C and provides an output current capability of 10mA. Packaged in an 8-SOIC surface-mount format, it supports operation across a temperature range of -40°C to 125°C.

Feature Summary

• Provides stable fixed voltage reference output
• Features low noise performance for precision applications
• Offers high initial accuracy and low drift characteristics

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Medical instrumentation signal conditioning

Procurement Notes

Verify the specific suffix 'AIDR' matches the required accuracy grade and tape-and-reel packaging configuration. Confirm that the 8-SOIC footprint aligns with the target PCB layout. Ensure the operating environment stays within the specified thermal limits for long-term stability.

Selection Notes

Select this component when a fixed 2.048V reference with ±0.1% accuracy is required. Consider the 1.2mA quiescent current for power-sensitive designs. The 8-SOIC package is suitable for automated surface-mount assembly processes.

Part Context

This part belongs to the REF50xx family of precision voltage references designed for industrial and automotive applications. It complements other variants in the series that offer different output voltages or accuracy grades while maintaining similar low-noise and low-drift specifications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as REF5025AIDR or REF5030AIDR, if different voltage levels are needed. Verify electrical parameter compatibility before substitution.
