PCM2903BDBR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This ensures proper device operation and prevents latch-up.
  • To optimize the analog input impedance, use a series resistor (Rs) and a capacitor (Cs) in parallel with the input signal. The values of Rs and Cs depend on the specific application and input signal characteristics.
  • The maximum allowed clock jitter for the PCM2903BDBR is 100 ps. Exceeding this value may result in errors in the ADC conversion process.
  • Yes, the PCM2903BDBR can be used in a multi-channel audio application. However, each channel requires a separate ADC and DAC, and the device must be properly synchronized to ensure proper operation.
  • The digital output data from the PCM2903BDBR is in 24-bit, 2's complement format. The data should be handled accordingly, taking into account the specific requirements of the downstream digital signal processing stages.
