TLV320AIC23BPWR datasheet by Texas Instruments

TLV320AIC23BPWR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TLV320AIC23BPWR?
  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.
• How do I configure the TLV320AIC23BPWR for stereo audio?
  To configure the TLV320AIC23BPWR for stereo audio, set the STEREO bit in the Audio Interface Control Register (AIC23_REG_04) to '1'. This enables stereo mode and allows for independent left and right channel audio processing.
• What is the maximum clock frequency supported by the TLV320AIC23BPWR?
  The TLV320AIC23BPWR supports clock frequencies up to 50 MHz. However, the recommended clock frequency is 12.288 MHz for optimal performance.
• How do I implement a microphone bias voltage using the TLV320AIC23BPWR?
  The TLV320AIC23BPWR has a built-in microphone bias voltage generator. To enable it, set the MICBIAS bit in the Power Management Register (AIC23_REG_03) to '1'. The microphone bias voltage can be adjusted using the MICBIAS_LEVEL bits in the same register.
• What is the purpose of the NOISE_GATE bit in the TLV320AIC23BPWR?
  The NOISE_GATE bit in the Audio Interface Control Register (AIC23_REG_04) enables a noise gate function that helps reduce noise and hiss in the audio signal. When set to '1', the noise gate is enabled, and the device will automatically mute the audio signal when the input level falls below a certain threshold.
