Codecs Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or obsolete inventory. Ensure compatibility with existing system designs before procurement due to end-of-life status.

Codecs Selection Notes

Select this part for applications requiring AC'97 2.3 compliance with integrated microphone pre-amps. Verify that the system design accommodates the specific +3.3 V analog supply requirement. Consider pin-compatible alternatives like the STAC9752A if +5 V analog supply support is needed instead.

Codecs Part Context

The STAC9753 series belongs to a family of AC'97 codecs from Tempo Semiconductor (now Renesas). It is pin-compatible with the STAC9750, STAC9752, and STAC9766 models. The primary distinction lies in the analog power supply voltage, where the STAC9753 variant specifically targets +3.3 V operation compared to other variants in the lineup.

Codecs Replacement Considerations

Public confirmed substitute part numbers include STAC9752AXTAED1XR and STAC9753XXTAEXR. These parts share pin compatibility but may differ in analog supply voltage requirements or manufacturing origin.
