PCM1861DBTR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by AVDD, and then DVDD. This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the analog and digital components on opposite sides of the board. Also, keep the input and output traces short and away from noise sources.
  • The maximum input voltage that the PCM1861DBTR can handle is 2.1 Vrms. Exceeding this voltage may cause distortion or damage to the device.
  • To configure the PCM1861DBTR for 24-bit or 32-bit audio, set the appropriate bits in the control register. For 24-bit audio, set bits [23:16] to 0, and for 32-bit audio, set bits [31:24] to 0. Refer to the datasheet for the specific register settings.
  • The recommended clock frequency for the PCM1861DBTR is 256 fs, where fs is the sampling frequency. This ensures that the device operates within its specified parameters.
