PCM1850APJT Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper internal biasing and prevents any potential damage to the device.
  • To minimize noise and EMI, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces as short as possible. Additionally, use a ferrite bead or a pi-filter to filter the power supply lines.
  • The maximum input signal amplitude that the PCM1850APJT can handle is 2.5Vrms, which is the maximum rating for the analog input pins. Exceeding this amplitude may result in distortion or damage to the device.
  • To configure the PCM1850APJT for master mode operation, set the M/S pin high and the BCK pin low. This will enable the internal clock generator and allow the device to operate as a master device.
  • The recommended clock frequency for the PCM1850APJT is 256fs, where fs is the sampling frequency. This ensures proper operation and minimizes jitter and noise.
