TLV320AIC34IZAS Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
  • To configure the TLV320AIC34IZAS for stereo audio, set the STEREO bit in the Audio Interface Control Register (AIC34_REG_03) to '1'. This enables stereo mode and allows for independent left and right channel audio processing.
  • The TLV320AIC34IZAS supports clock frequencies up to 50 MHz. However, the recommended clock frequency is 12.288 MHz for optimal performance.
  • The TLV320AIC34IZAS has a built-in microphone bias voltage generator. To implement a microphone bias voltage, connect the MIC_BIAS pin to the microphone and set the MIC_BIAS_EN bit in the Audio Interface Control Register (AIC34_REG_03) to '1'. The device will then generate a 2.2V bias voltage.
  • The NOISE_GATE_EN bit enables or disables the noise gate function, which is used to reduce noise and hiss in the audio signal. When set to '1', the noise gate function is enabled, and the device will automatically mute the audio signal when the input level falls below a certain threshold.
