Overview
The REF5045AIDR is a precision series voltage reference manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It provides a fixed output voltage of 4.5 V with an initial accuracy of 0.05% and a temperature coefficient of 3 PPM/C. The device operates within an input voltage range up to 18 V and supports a maximum shunt current of 10 mA. Quiescent current consumption is specified at 800 uA. The component functions reliably across an extended industrial temperature range from -40 C to +125 C.
Feature Summary
- Delivers high-precision voltage regulation with low noise characteristics suitable for sensitive analog circuits.
- Maintains stable output performance over wide temperature variations due to very low drift specifications.
- Designed for efficient power management with low quiescent current operation.
Applications
- High-resolution data acquisition systems requiring stable reference sources
- Precision instrumentation amplifiers and signal conditioning circuits
- Calibration equipment demanding high initial accuracy
Procurement Notes
Verify the specific suffix IDR confirms the SOIC-8 tape-and-reel packaging configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the official datasheet. Confirm that the 0.05% accuracy grade meets system requirements before integration.
Selection Notes
Select this component when a 4.5 V reference is required with tight tolerance and low thermal drift. Compare against the REF5045EIDR if lower noise or higher input voltage capability is needed. Consider the REF5045AID tube variant if reel packaging is not preferred for assembly processes.
Part Context
This part belongs to the REF5045 family of precision voltage references from Texas Instruments. It shares core electrical specifications with other variants like the REF5045AID but differs in packaging format. The family is categorized under PMIC voltage references designed for industrial and measurement applications.
Replacement Considerations
The REF5045AID serves as a tube-packaged alternative with identical electrical characteristics. The REF5045AIDG4 is a legacy version of the same specification. Verify pinout and thermal performance when substituting these equivalents.
