PCM1803DBR 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 the device.
  • 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 PCM1803DBR is between 256 fs and 512 fs, where fs is the sampling frequency. This ensures proper device operation and minimizes jitter and noise.
  • The digital output data from the PCM1803DBR is in 24-bit two's complement format. The data should be handled as unsigned data, and the most significant bit (MSB) should be used as the sign bit. The data should also be processed in a way that maintains the correct byte alignment.
  • The recommended layout and routing for the PCM1803DBR involves keeping the analog and digital signals separate, using a ground plane to reduce noise, and minimizing the length of the analog input traces. The device should also be placed close to the analog input signals to minimize noise and interference.
