title: Texas Instruments TLV320AIC3x Codec

description: |
  TLV320AIC3x are a series of low-power stereo audio codecs with stereo
  headphone amplifier, as well as multiple inputs and outputs programmable in
  single-ended or fully differential configurations.
 
  The serial control bus supports SPI or I2C protocols, while the serial audio
  data bus is programmable for I2S, left/right-justified, DSP, or TDM modes.
 
  The following pins can be referred in the sound node's audio routing property:
 
  CODEC output pins:
     LLOUT
     RLOUT
     MONO_LOUT
     HPLOUT
     HPROUT
     HPLCOM
     HPRCOM
 
  CODEC input pins for TLV320AIC3104:
     MIC2L
     MIC2R
     LINE1L
     LINE1R
 
  CODEC input pins for other compatible codecs:
     MIC3L
     MIC3R
     LINE1L
     LINE2L
     LINE1R
     LINE2R
