+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
