Procurement Notes

Verify the manufacturer part number RS8561XF against official Runic Technology documentation to confirm pinout and electrical tolerances. Ensure the selected packaging variant (Tape & Reel, Cut Tape, or Digi-Reel) matches assembly requirements. Confirm RoHS3 compliance status if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a single-channel amplifier with rail-to-rail output is required in a compact SOT-23-5 footprint. The low input offset voltage makes it suitable for high-accuracy applications. Verify that the 1.3 mA supply current fits the system power budget and that the 11 MHz bandwidth meets signal frequency requirements.

Part Context

The RS8561XF belongs to the Runic Technology RS856x series of precision operational amplifiers. This series targets applications requiring small form factors and high performance. The XF suffix typically denotes specific packaging or testing configurations within the manufacturer's lineup, distinct from other variants in the same functional family.

Replacement Considerations

Consult official substitution guides for direct equivalents. Generic replacements may differ in offset voltage or supply current specifications.
