REF6045IDGKR

Overview

The REF6045IDGKR is a high-precision series voltage reference IC manufactured by Texas Instruments. It provides a fixed output voltage of 4.5 V with an initial accuracy of ±0.05%. The device features an excellent temperature drift performance of 5 ppm/°C maximum over the operating temperature range of -40°C to +125°C. It operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 3.5 mA. The component is housed in an 8-pin VSSOP package, suitable for surface-mount applications.

Feature Summary

• Delivers high-precision voltage regulation with minimal temperature drift
• Integrates internal buffering for stable output drive capability
• Includes an enable pin for power management control

Applications

• Precision data acquisition systems
• Medical instrumentation requiring stable reference voltages
• Industrial process control loops

Procurement Notes

Verify the specific suffix 'DGKR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-VSSOP footprint matches the target PCB design constraints. Ensure compatibility with the system's input voltage limits relative to the 5.5 V maximum rating. Validate thermal management requirements for the specified operating temperature range.

Selection Notes

Select this component when a fixed 4.5 V reference with low drift is required. The integrated buffer simplifies circuit design by eliminating external components. Consider the VSSOP-8 package size for space-constrained layouts. Compare against other REF60 variants if different output voltages or noise specifications are needed.

Part Context

This part belongs to the REF60 family of precision voltage references from Texas Instruments. The family is characterized by low noise and high stability. The REF6045 variant specifically targets applications needing a 4.5 V rail. The DGKR suffix indicates the reel packaging option for high-volume manufacturing.

Replacement Considerations

Direct substitutes include other REF60 series parts with compatible packages and electrical characteristics. Verify pinout compatibility before swapping. Alternative families may require circuit redesign due to differing buffer configurations or noise profiles.
