Overview
The REF5040IDG4 is a precision voltage reference IC from Texas Instruments, featuring a fixed output of 4.096 V with an initial accuracy of ±0.05%. It operates within an input voltage range of 4.296 V to 18 V and supports a maximum load current of 10 mA. The device exhibits a low temperature coefficient of 3 ppm/°C and consumes 800 µA of supply current. It is housed in an 8-SOIC package, rated for operation between -40°C and +125°C, and includes noise performance of 12 µVpp/V in the 0.1 Hz to 10 Hz band.
Feature Summary
- Provides high-precision fixed voltage reference with tight initial accuracy tolerance
- Features very low drift characteristics suitable for sensitive measurement applications
- Operates efficiently with low quiescent current consumption
Applications
- High-resolution data acquisition systems
- Precision analog-to-digital converter references
- Calibration equipment requiring stable voltage standards
Procurement Notes
Verify the specific suffix 'DG4' against the manufacturer's latest documentation to confirm current production status and pinout compatibility. Ensure the 8-SOIC package dimensions match the target PCB footprint. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.
Selection Notes
Select this component when a 4.096 V output is required with strict accuracy constraints. Consider the 8-SOIC package size for space-constrained designs. Evaluate the 3 ppm/°C temperature coefficient against environmental operating ranges. Compare power consumption needs against the 800 µA supply current specification.
Part Context
This part belongs to the REF50xx series of precision voltage references designed for demanding industrial and instrumentation applications. The series offers various output voltages and accuracy grades. The IDG4 designation indicates a specific tape-and-reel packaging option within the SOIC-8 form factor family.
Replacement Considerations
REF5040IDR serves as a direct functional equivalent with identical electrical specifications but differs in packaging format. Verify that the alternative package type meets mechanical assembly requirements.
