Application Scenarios & Design Considerations

VOICE-BAND AUDIO PROCESSOR

Alternative Part Number

  • LM4935TLX/NOPB --: Audio codec with similar voice-band ADC/DAC functionality, same manufacturer and supply ecosystem, suitable as a functional substitute in audio front-end designs.
  • AD73311ARSZ --: Low-cost voice-band analog front-end codec with comparable ADC/DAC performance, widely used as a cross-vendor alternative for telephony audio interfaces.
  • MC145480DW --: Voice-band PCM codec/filter with similar serial interface and audio conversion role, offering a second-source option when TI parts are unavailable.
