RF Receivers Procurement Notes

Verify the specific suffix 'C40' against current manufacturer documentation, as datasheets often reference the 'D60' variant. Confirm availability status, as older revisions may be discontinued or subject to last-time-buy notices. Ensure the 24-SSOP package matches the target PCB footprint and that the 2V minimum supply voltage aligns with system power requirements.

RF Receivers Selection Notes

Select this component when a dedicated AM/FM receiver in a 24-SSOP package is required. Compare against the SI4730-D60-GUR if a different package or updated revision is preferred. Verify that the 2V to 5.5V supply range fits the design. Check for direct replacements like the D60 series if C40 stock is limited.

RF Receivers Part Context

This part belongs to the Si4730 family of single-chip AM/FM radio tuners. It is distinct from other variants such as the SI4735 or SI4736, which support additional bands like Shortwave or Weather Band. The C40 suffix typically denotes a specific package type and revision within the broader product line.
