PCM1796DB 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, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the signal traces short and away from noise sources.
  • The maximum clock frequency for the PCM1796DB is 128 fs (384 kHz), but it can be overclocked to 192 fs (576 kHz) with reduced performance.
  • The digital filter coefficients can be calculated using the TI-provided filter coefficient calculator tool or by using a third-party tool. The coefficients should be loaded into the device during initialization.
  • The recommended operating temperature range for the PCM1796DB is -40°C to 85°C, but it can operate up to 105°C with reduced performance.
