Application Scenarios & Design Considerations

Low Power, Highly Integrated Audio Codec with Headphone Amplifier

Alternative Part Number

  • WM8731SEDS --: Stereo audio codec with integrated headphone driver and similar I2S/PCM interface, a common drop-in functional alternative to the TLV320AIC23B.
  • AK4556VT --: Low-power 24-bit stereo audio codec with comparable ADC/DAC performance and serial audio interface, suitable as a functional replacement.
  • MAX9867ETJ+ --: Ultra-low-power stereo audio codec with similar feature set and I2S interface, offering comparable functionality in a different package option.
  • TLV320AIC23BIPWR --: Same TLV320AIC23B stereo audio codec family in a TSSOP package, functionally equivalent with different package and pinout, suitable for space-constrained designs.
  • TLV320AIC23BPW --: Same codec die in TSSOP package, drop-in functional replacement when BGA is not required; widely available and lower cost.
  • TLV320AIC23BIRHDR --: Same audio codec in a smaller QFN package, good alternative when board area is limited and reflow assembly is acceptable.
