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:
