PCM1808PWR Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog power supplies (VAA and VDDA). This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the analog input impedance, use a low-impedance source (e.g., a buffer amplifier) and keep the input cables short to minimize capacitive loading. Also, ensure that the input signal is properly terminated to prevent signal reflections.
  • The maximum allowed clock jitter for the PCM1808PWR is 50 ps RMS. Exceeding this limit can result in decreased converter performance and increased distortion.
  • Yes, the PCM1808PWR can be used in a multi-channel audio application. However, each channel requires a separate converter, and the master clock must be synchronized across all channels to ensure proper operation.
  • The PCM1808PWR outputs 24-bit data in I²S format. The digital output data should be captured and processed by a microcontroller or DSP, taking care to handle the data correctly to avoid errors and ensure proper audio playback.
