REF5020IDGKR

Overview

The REF5020IDGKR is a precision voltage reference from Texas Instruments, housed in an 8-pin VSSOP package. It delivers a fixed output of 2.048 V with an initial accuracy of 0.05%. The device features a low temperature coefficient of 3 ppm/°C and operates within a junction temperature range of -40°C to +125°C. It supports a maximum shunt current of 10 mA and requires a minimum input voltage of 2.5 V. This component is designed for high-precision applications requiring stable reference voltages under varying thermal conditions.

Feature Summary

• Provides a fixed 2.048 V output with high initial accuracy
• Features ultra-low temperature coefficient for thermal stability
• Operates reliably across extended industrial temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix IDGKR confirms the VSSOP-8 package and tape-and-reel packaging format. Ensure the order matches the required 2.048 V output variant. Confirm that the supplier provides traceability documentation consistent with Texas Instruments manufacturing standards for this specific part number.

Selection Notes

Select this component when a fixed 2.048 V reference is required with stringent accuracy and drift specifications. The VSSOP-8 package suits space-constrained designs. Consider the 10 mA load capability and 3 ppm/°C drift rate against system requirements. Compare against other ADR series parts if different output voltages or package types are needed.

Part Context

This part belongs to the REF50xx family of precision voltage references. It complements other Texas Instruments components like the REF50xx series variants offering different fixed voltages. The device integrates bandgap reference technology optimized for low noise and high stability, serving as a critical benchmark element in mixed-signal circuits.

Replacement Considerations

Direct substitutes include other REF5020 variants with compatible packages. Cross-reference with Analog Devices ADR421 or ADR431 series if pin compatibility and electrical specs align. Verify package dimensions and thermal characteristics before substitution.
