PCM1690DCAR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
  • To optimize ADC performance, ensure that the analog input signal is within the recommended range, use a low-pass filter to remove high-frequency noise, and adjust the ADC clock frequency to minimize jitter and noise.
  • The maximum allowed capacitance for the analog input pins is 10nF. Exceeding this value may affect the ADC's performance and accuracy.
  • The PCM1690DCAR outputs 24-bit data in I²S format. Ensure that your microcontroller or digital signal processor can handle this format and that you have implemented the necessary synchronization and data processing logic.
  • Keep analog and digital signals separate, use a ground plane to reduce noise, and route analog signals away from digital signals. Use a 4-layer PCB with a dedicated analog ground plane and a separate digital ground plane.
