| 8 | title: Texas Instruments TLV320AIC3x Codec |
| 9 | |
| 10 | description: | |
| 11 | TLV320AIC3x are a series of low-power stereo audio codecs with stereo |
| 12 | headphone amplifier, as well as multiple inputs and outputs programmable in |
| 13 | single-ended or fully differential configurations. |
| 14 | |
| 15 | The serial control bus supports SPI or I2C protocols, while the serial audio |
| 16 | data bus is programmable for I2S, left/right-justified, DSP, or TDM modes. |
| 17 | |
| 18 | The following pins can be referred in the sound node's audio routing property: |
