Application Scenarios & Design Considerations

Low Power, Highly Integrated Audio Codec with Headphone Amplifier

Alternative Part Number

  • TLV320AIC23BPW --: Same TLV320AIC23B stereo audio codec die in a TSSOP package instead of TSSOP-with-tape-and-reel; electrically identical, only packaging differs, so it is the closest drop-in choice when reel packing is not required.
  • TLV320AIC23BIRHDR --: Same codec family and function with the industrial temperature grade, supplied in a smaller VQFN package; a good alternative when board space is tight and a re-layout is acceptable.
  • WM8731CLSEFL --: Comparable low-power stereo audio codec with I2S interface and headphone/speaker drivers from another vendor; requires pin and register rework but is a well-established functional substitute for the TLV320AIC23B.
  • TLV320AIC23BIRHD --: Same codec die in a smaller VQFN package; good alternative when board space is tight, with equivalent audio performance and register compatibility.
