PCM1795DB 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 minimize noise and ensure optimal performance, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signal traces separate and away from each other.
  • The maximum clock frequency for the PCM1795DB is 128 fs (fs = sampling frequency). However, it's recommended to use a clock frequency of 256 fs or less to ensure optimal performance.
  • The digital filter coefficients are stored in the device's internal ROM. However, you can also use external coefficients by programming them into the device's registers. Refer to the datasheet for the correct programming sequence.
  • The recommended operating temperature range for the PCM1795DB is -40°C to 85°C. However, the device can operate up to 105°C with reduced performance and reliability.
