2.5.1 Audio Input/Output

The EVM supports stereo headset audio via a 3.5mm audio jack [J21]. Texas Instruments TLV320AIC3106 provides the audio conversions (DAC and ADC). The audio output conversion supports sampling rates of 8KHz to 96KHz. The audio input includes pre-amp and automatic gain control. The audio codec also integrates the headphone driver and microphone bias circuits.
