REF5025IDGKR

Overview

The REF5025IDGKR is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 2.7 V to 18 V and supports a maximum load current of 10 mA while consuming only 1.2 mA of supply current. It features a low temperature coefficient of 3 ppm/°C and exhibits low noise characteristics, specifically 7.5 µVpp from 0.1 Hz to 10 Hz. The component is housed in an 8-VSSOP package and is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerance.
• Maintains stable performance over wide temperature variations with minimal drift.
• Provides low-noise output suitable for sensitive analog signal processing applications.

Applications

• Medical equipment requiring precise voltage references
• Data acquisition systems
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix 'DGKR' corresponds to the 8-VSSOP package and reel packaging configuration. Confirm RoHS compliance status matches REACH regulations. Ensure the operating temperature range aligns with system requirements. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision history before procurement.

Selection Notes

Select this component when a fixed 2.5 V reference with high precision is required. Consider the 8-VSSOP package size for space-constrained designs. Evaluate the 10 mA output current capability against load requirements. Verify that the 3 ppm/°C temperature coefficient meets the system's stability needs. Compare power consumption specifications if battery life is a critical design constraint.

Part Context

This part belongs to the REF50xx family of precision voltage references from Texas Instruments. The family offers various output voltages and packages while maintaining similar performance characteristics such as low noise and high accuracy. The REF5025 variant specifically targets applications needing a 2.5 V reference point. The IDGKR suffix indicates the industrial temperature grade and surface-mount packaging type.

Replacement Considerations

Publicly confirmed substitute part numbers include REF5025IDGKT for tape-and-reel variants in the same package. Other package options like REF5025ID are available for through-hole or different surface-mount footprints. Verify pin compatibility and electrical specifications before substituting with other manufacturers' parts.
