REF6045IDGKT

Overview

The REF6045IDGKT 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 a low temperature coefficient of 5 ppm/°C, ensuring stable performance across varying thermal conditions. It operates within an input voltage range of 4.75 V to 5.5 V and draws a supply current of 1.15 mA. The unit is housed in an 8-VSSOP surface-mount package and supports a maximum shunt current of 3.5 mA.

Feature Summary

• Delivers a fixed 4.5 V output with high precision and low drift
• Features ultra-low noise characteristics for sensitive signal chains
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Medical instrumentation requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'DGKT' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the 8-VSSOP footprint matches the target PCB layout dimensions. Ensure the operating environment stays within the specified temperature range to maintain the stated accuracy specifications. Cross-reference the manufacturer datasheet for any recent design revisions or compliance updates before finalizing procurement.

Selection Notes

Select this component when a stable 4.5 V reference is required with tight initial accuracy and low temperature drift. It is suitable for applications demanding low noise performance in compact form factors. Compare against other REF62xx series variants if different output voltages or package types are needed. Ensure the input voltage supply remains within the 4.75 V to 5.5 V operational window for proper regulation.

Part Context

This part belongs to the REF62xx family of precision voltage references from Texas Instruments. These devices are designed for applications requiring high accuracy and stability. The REF6045IDGKT specifically offers a 4.5 V output, distinguishing it from other members of the series that provide different voltage levels such as 2.5 V or 5 V while sharing similar architectural benefits.

Replacement Considerations

Direct substitutes include other REF6045 variants with different packaging options, such as REF6045IDKR. For different output voltages within the same precision class, consider REF6225 or REF6250 series components. Verify pin compatibility and thermal requirements when substituting with packages from other manufacturers.
