Application Scenarios & Design Considerations

Low Power Low IOVdd Dual Channel Codec With Headset/Handset/Speaker Driver

Alternative Part Number

  • WM8731CLSEFL --: Stereo audio codec with similar I2S interface and integrated headphone driver, commonly used as a TI codec alternative.
  • MAX9867ETJ+ --: Low-power stereo audio codec with I2S/PCM interface, comparable functionality to the TLV320AIC21 in portable audio designs.
  • SGTL5000XNLA3 --: Low-power stereo codec with headphone amp and I2S interface, widely used as a drop-in functional alternative for TI audio codecs.
  • TLV320AIC23BIPWR --: Same TLV320AIC audio codec family with stereo DAC/ADC and headphone amp, similar I2S interface and TQFP package; widely available and often used as a drop-in upgrade in audio designs.
  • AK4556VT --: Low-power 24-bit stereo audio codec with I2S interface and small TSSOP package, offering similar audio performance and a different vendor/series for design flexibility.
