TLV320AIC34IZASR datasheet by Texas Instruments

TLV320AIC34IZASR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TLV320AIC34IZASR?
  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 TLV320AIC34IZASR for master or slave mode?
  The TLV320AIC34IZASR can be configured for master or slave mode by setting the M/S bit in the Control Register (CR) to 1 for master mode or 0 for slave mode.
• What is the maximum clock frequency supported by the TLV320AIC34IZASR?
  The TLV320AIC34IZASR supports clock frequencies up to 50 MHz.
• How do I implement a microphone bias voltage using the TLV320AIC34IZASR?
  The TLV320AIC34IZASR has a built-in microphone bias voltage generator that can be enabled by setting the MIC_BIAS_EN bit in the Control Register (CR). The bias voltage can be set to 1.5V, 2.0V, or 2.5V using the MIC_BIAS_SEL bits.
• What is the purpose of the NOISE_GATE_EN bit in the Control Register (CR)?
  The NOISE_GATE_EN bit enables or disables the noise gate function, which is used to reduce noise and hiss in the audio signal.
