title: Texas Instruments TAC5X1X Codec
description: |
TAC5X1X are series of low-power and high performance mono or stereo
audio codecs, as well as multiple inputs and outputs programmable in
single-ended or fully differential configurations. Device supports both
Microphone and Line In input on ADC Channel. DAC Output can be configured
for either Line Out or Head Phone Load.
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.
Specification about the codecs can be found at:
