PCM1808PW Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures that the internal voltage regulators are powered up correctly.
  • The analog input filter should be designed to reject noise and interference above 20 kHz. A simple RC filter with a cutoff frequency around 10 kHz to 15 kHz is recommended. The filter should also be designed to minimize signal attenuation and distortion.
  • The recommended clock frequency for the PCM1808PW is 256 fs, where fs is the sampling frequency. This ensures that the ADC operates at the optimal frequency for maximum performance.
  • The digital output data from the PCM1808PW is in 24-bit two's complement format. The data should be latched on the rising edge of the BCK clock signal. The data should also be synchronized with the LRCK clock signal to ensure correct channel identification.
  • The recommended layout and routing for the PCM1808PW involves separating the analog and digital sections of the board, using a solid ground plane, and minimizing signal traces near the ADC inputs. The analog input traces should be short and direct, and the digital output traces should be shielded to minimize EMI.
