Voltage Reference Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific package variant. Confirm that the SOIC-8 footprint matches your PCB layout requirements. Check the datasheet for thermal considerations during soldering. Ensure the operating environment stays within the specified 0°C to +70°C range for optimal accuracy. Validate supply chain authenticity through authorized distributors.

Voltage Reference Selection Notes

Choose this component when a 2.048 V output is required with tight initial accuracy tolerances. The low temperature coefficient makes it suitable for environments with moderate thermal variations. Consider the 8 mA maximum shunt current limit for load regulation needs. Compare against higher precision or wider temperature range alternatives if application demands exceed these specifications. Evaluate power budget constraints due to its micropower architecture.

Voltage Reference Part Context

This device belongs to the LM4140 series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The CCM suffix indicates the SOIC-8 surface-mount package option. The NOPB designation confirms non-lead-based construction compliant with environmental standards. This family targets cost-sensitive applications requiring reliable voltage referencing without complex external components.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4140 variants with different output voltages or accuracies, such as LM4140ACM-2.0/NOPB. Cross-reference pinouts and thermal characteristics before substitution. Verify that alternative packages maintain compatibility with existing footprints. Consult official TI documentation for detailed electrical parameter comparisons between series members.
