Codecs Procurement Notes

Verify the specific ordering suffix to ensure the correct package type, as variations exist between tube and reel packaging options. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision level before procurement.

Codecs Selection Notes

Select this component when a single-chip solution for PCM audio conversion is required alongside filtering functions. Ensure the system design accommodates the 20-SOIC surface mount footprint and operates within the specified temperature range. Consider the 125kbps data rate requirement to match the application's bandwidth needs without additional external multiplexing hardware.
