TLV320AIC23BIPWR datasheet by Texas Instruments

TLV320AIC23BIPWR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TLV320AIC23BIPWR?
  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 TLV320AIC23BIPWR for master or slave mode?
  The TLV320AIC23BIPWR can be configured for master or slave mode by setting the M/S bit in the Control Register (address 0x00). A value of 0 sets the device to slave mode, while a value of 1 sets it to master mode.
• What is the maximum clock frequency supported by the TLV320AIC23BIPWR?
  The TLV320AIC23BIPWR supports clock frequencies up to 50 MHz.
• How do I implement a microphone bias voltage using the TLV320AIC23BIPWR?
  The TLV320AIC23BIPWR has a built-in microphone bias voltage generator. To implement it, connect the MIC_BIAS pin to the microphone, and set the MIC_BIAS_EN bit in the Control Register (address 0x00) to 1.
• What is the purpose of the NOISE_GATE pin on the TLV320AIC23BIPWR?
  The NOISE_GATE pin is used to enable or disable the noise gate function, which helps to reduce noise and hiss in the audio signal. When the pin is high, the noise gate is enabled, and when it's low, it's disabled.
