Procurement Notes

Verify the 'G4' suffix indicates lead-free compliance and RoHS standards as per Texas Instruments documentation. Confirm the specific package marking and date code align with project requirements. Ensure the supplier provides valid traceability documents. Cross-reference the full part number against the official TI datasheet to confirm availability status and any recent manufacturing changes.

Selection Notes

Select this component when an adjustable reference voltage between 1.225V and 10V is required with high precision. The ±0.5% tolerance and 100ppm/°C temperature coefficient suit industrial environments. The SOT-23-3 package is ideal for space-constrained designs. Verify that the load current requirements fall within the specified operational range for stable regulation.

Part Context

This device belongs to the LM4041 family of micropower shunt voltage references. It shares core architectural features with other variants in the series but is distinguished by its adjustable output configuration and C-grade accuracy specifications. The family is designed for general-purpose precision referencing in power management and signal conditioning circuits.

Replacement Considerations

LM4041CIDBZT: Identical functional specifications and package; verify if the G4 suffix denotes specific environmental compliance differences.
