REF5025AID

Overview

The REF5025AID is a series voltage reference integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.1%. The device operates within an input voltage range of 2.7V to 18V and draws a supply current of 1.2mA. It supports a maximum output current of 10mA and features a temperature coefficient of 8ppm/°C. Low-frequency noise is specified at 7.5µVpp/V from 0.1Hz to 10Hz. The component functions reliably across an ambient temperature range of -40°C to 125°C.

Feature Summary

• Provides stable fixed voltage reference with high initial accuracy
• Features low noise performance for precision signal integrity
• Supports bidirectional current sourcing and sinking capabilities
• Operates over extended industrial temperature ranges

Applications

• High-precision data acquisition systems
• Medical instrumentation such as ECG circuits
• Industrial process control and automation
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'ID' confirms the 8-SOIC package and ±0.1% accuracy grade, distinct from other REF5025 variants like the IDG4 or AIDR which may differ in packaging or reel specifications. Confirm RoHS3 compliance status for environmental regulations. Check moisture sensitivity level (MSL 2) requirements for soldering processes. Ensure the supplier source matches the manufacturer's official distribution channels to guarantee authenticity.

Selection Notes

Select this component when a 2.5V reference with ±0.1% accuracy is required in an SOIC-8 footprint. Compare against lower accuracy grades if cost is critical, or higher accuracy grades like the REF5025ID if tighter tolerances are needed. Consider the 8ppm/°C drift rate against system thermal stability requirements. Evaluate the 1.2mA supply current against power budget constraints in portable or battery-operated designs.

Part Context

This part belongs to the REF5025 family of precision voltage references from Texas Instruments. The family includes variants with different accuracies (±0.05%, ±0.1%) and packages (SOIC, VSSOP). The REF5025AID specifically denotes the 0.1% accuracy version in the standard SOIC-8 package, offering a balance between precision and form factor for general-purpose high-performance analog applications.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the REF5025ID for higher accuracy. Cross-manufacturer equivalents should be verified for pinout compatibility and electrical parameter matching, particularly regarding output current capability and temperature coefficient.
