Procurement Notes
Verify the specific ordering suffix against official Tempo Semiconductor documentation to confirm pinout and package variations. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Ensure compatibility with Intel HD Audio interface requirements before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring integrated speaker and headphone amplification alongside standard codec functions. Verify that the design utilizes either +5 V or +3.3 V analog supply rails. Consider the 40-pin QFN footprint constraints during PCB layout planning.
Part Context
This part belongs to the 92HD65C series of single-chip PC audio systems. It consolidates codec, amplifier, and power regulation functions into one package. The series targets mainstream consumer electronics requiring high-fidelity audio processing.
Replacement Considerations
Check for IDT92HD65C5X5NDGXZBX as a potential alias. Verify electrical pinouts and software configuration registers before substituting with other members of the 92HD65C family.
