ES9822QPRO Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal (MCLK).
  • To configure the ES9822QPRO for master clock mode, set the MCLK pin as the clock source, and set the BCLK pin as the output clock. The MCLK frequency should be set to 256 times the desired sample rate.
  • The maximum input signal level for the ADC inputs is 2.5 Vpp (peak-to-peak) for a 0 dBFS (decibel full scale) signal.
  • The ES9822QPRO has an internal microphone bias voltage generator. To enable it, connect the MIC_BIAS pin to the desired microphone bias voltage (typically 2.5 V) through a 1 kΩ resistor.
  • The latency of the ES9822QPRO's ADC is approximately 1.5 ms, and the latency of the DAC is approximately 1.2 ms.
