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
