Audio Special Purpose Procurement Notes

The SA575DG is listed as Obsolete/End-of-Life by onsemi. Procurement should focus on remaining stock from authorized distributors or consider replacement parts. Verify RoHS status if required, as older batches may not be compliant.

Audio Special Purpose Part Context

The SA575DG belongs to the SA575 family of precision dual gain control circuits. The 'DG' suffix indicates the SOIC-20 surface-mount package variant. Other variants include the DIP package (SA575N) and TSSOP package (SA575DTB).

Audio Special Purpose Replacement Considerations

As the SA575DG is obsolete, designers should evaluate alternative dual-channel compandors or single-channel solutions depending on system requirements. Check onsemi's product change notices for any recommended replacements.
