PCM1863DBT Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by AVDD, and then DVDD. This ensures that the internal voltage regulators are powered up correctly.
  • The analog input filter should be optimized based on the specific application requirements. A good starting point is to use a 1st-order RC filter with a cutoff frequency of around 100 kHz to 200 kHz. The filter components should be chosen to minimize noise and distortion.
  • The maximum input signal amplitude that the PCM1863DBT can handle is 2.5 Vrms. Exceeding this amplitude may result in distortion and decreased performance.
  • To configure the PCM1863DBT for differential input mode, connect the positive input signal to the INP pin and the negative input signal to the INN pin. Ensure that the input common-mode voltage is within the recommended range of 0.5 V to 2.5 V.
  • The recommended clock frequency for the PCM1863DBT is 256 fs, where fs is the sampling frequency. This ensures that the ADC operates within its specified performance range.
