REF5025IDR

Overview

The REF5025IDR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of ±0.05%. It features a low temperature coefficient of 3 ppm/°C and operates within an input voltage range of 2.7 V to 18 V. The device supports a maximum load current of 10 mA while consuming approximately 800 µA of supply current. It is housed in an 8-SOIC package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision voltage regulation with very low drift characteristics for stable reference performance.
• Features low noise output suitable for sensitive analog signal processing applications.
• Includes shutdown functionality to minimize power consumption during inactive periods.

Applications

• Medical ECG systems requiring precise voltage references
• High-resolution data acquisition systems
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix ID against the official datasheet to confirm the ±0.05% accuracy grade and 3 ppm/°C drift specification. Ensure the SOIC-8 package matches the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements before finalizing procurement orders.

Selection Notes

Select this component when application requirements demand ultra-low drift and low noise alongside moderate accuracy. Compare against higher accuracy variants like the REF5025EIDR if tighter tolerance is needed. Consider the REF5025AIDR if slightly lower cost is acceptable with reduced precision specifications.

Part Context

This part belongs to the REF50xx family of precision voltage references designed for demanding measurement applications. It complements other outputs in the series such as 1.25 V, 2.048 V, and 5.0 V options, providing designers with standardized reference solutions for various ADC and DAC interfaces.

Replacement Considerations

ADR03ARZ is listed as a similar replacement option by Analog Devices Inc., offering comparable series reference functionality.
