Procurement Notes

Verify the specific suffix 'R2' corresponds to the reel quantity and tape configuration as defined in the official ordering guide. Confirm RoHS compliance status via the 'Z' designation in the part number. Ensure the selected grade matches the required accuracy specifications for the target application environment.

Selection Notes

Select this component when a stable 2.048 V reference is required in a minimal footprint. The ±0.1% accuracy grade is suitable for high-precision data acquisition. Consider the minimum operating current of 50 µA for low-power designs. Verify that the load current requirements fall within the specified 50 µA to 15 mA range for optimal performance.

Part Context

This part belongs to the ADR504x family of micropower shunt voltage references. The family includes variants with different output voltages such as 2.5 V, 3.0 V, 4.096 V, and 5.0 V. All members share similar architectural features, including bandgap technology and ultracompact packaging options like SC-70 and SOT-23.

Replacement Considerations

LM4040 and LM4050 series devices are pin-compatible alternatives. Verify electrical specifications against the original design requirements before substitution.
