Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package type matches the design footprint requirements. Ensure the operating temperature range meets the environmental constraints of the target application. Cross-reference the datasheet revision date to ensure all electrical characteristics are current.

Selection Notes

Select this component when a fixed 4.096V reference with high initial accuracy is required in a compact SOT-23-3 package. It is suitable for applications prioritizing low power consumption alongside precision. Consider the ±0.2% tolerance if tighter specifications are needed, or explore other grades within the family if cost sensitivity allows for lower precision options.

Part Context

This part belongs to the TL4050 series of precision micropower shunt voltage references from Texas Instruments. The series offers various output voltages and accuracy grades. The 'B' designation typically denotes the ±0.2% accuracy grade, while '41' specifies the 4.096V output voltage. The 'G4' suffix confirms environmental compliance.

Replacement Considerations

Direct pin-compatible replacements within the same family include TL4050B41IDBZR. Other compatible parts may include LM4040 series devices, though electrical characteristics and package dimensions should be verified against the original design requirements.
