PCM1802DBR Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signals. This ensures proper device operation and prevents damage.
  • To optimize the analog input stage, use a low-pass filter to remove high-frequency noise, and ensure the input signal is within the recommended range of 0.5V to 2.5V. Also, use a high-impedance source and a low-capacitance cable to minimize signal degradation.
  • The recommended clock frequency for the PCM1802DBR is between 2.4 MHz and 50 MHz. However, the optimal clock frequency depends on the specific application and sampling rate requirements.
  • To minimize clock jitter and phase noise, use a high-quality clock source, such as a crystal oscillator, and ensure the clock signal is clean and stable. You can also use a clock jitter attenuator or a phase-locked loop (PLL) to further reduce jitter and phase noise.
  • The maximum allowed input voltage for the PCM1802DBR is 3.6V. Exceeding this voltage can damage the device.
