Voltage Reference Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific 'R2' suffix corresponds to the required reel packaging configuration. Ensure the ordering part number matches the exact electrical grade and package type required for the design. Request original manufacturer documentation to validate specifications against the official datasheet.

Voltage Reference Selection Notes

Select this component when a stable 4.096 V reference is needed in space-constrained designs. The series topology eliminates the need for input series resistors found in shunt references, improving power efficiency. Verify that the system supply voltage remains above VOUT + 200 mV. Consider the ±0.98% initial accuracy and 100 ppm/°C drift if strict tolerance requirements exist.

Voltage Reference Part Context

This device belongs to the AD158x family of micropower precision references, which includes variants offering 2.5 V, 3 V, and 5 V outputs. All members share identical pinouts, package styles, and core architectural features. The AD1584 specifically targets applications requiring a 4.096 V standard compatible with common data converter systems.

Voltage Reference Replacement Considerations

Direct functional substitutes within the same family include AD1582ARTZ-R2 (2.5 V), AD1583ARTZ-R2 (3 V), and AD1585ARTZ-R2 (5 V). These parts share the same pinout and package but differ in output voltage.
