Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific automotive qualification requirements if applicable to the target environment. Review the latest datasheet revision for any specification updates before finalizing procurement specifications.

Selection Notes

Select this component when a precise 4.096 V reference is required in a minimal footprint. Ensure the bias resistor calculation accommodates the minimum 50 µA operating current at the lowest supply voltage and the maximum 15 mA limit at the highest supply voltage. Consider stacking multiple units if higher voltages are needed, noting that errors accumulate.

Part Context

This part belongs to the ADR504x family of precision shunt voltage references, which includes variants with different output voltages such as 2.048 V, 2.5 V, 3.0 V, and 5.0 V. The 'B' suffix indicates the ±0.1% accuracy grade, while 'KSZ' denotes the SC-70 package and RoHS compliance. These devices utilize band gap technology for stability.

Replacement Considerations

The datasheet explicitly states pin compatibility with LM4040 and LM4050 series components. Designers should verify electrical parameters against these equivalents to ensure functional interchangeability in existing circuits.
