PCM1803ADB Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This sequence helps prevent latch-up and ensures proper device operation.
  • To optimize the analog input filter design, use a low-pass filter with a cutoff frequency below 20 kHz to prevent aliasing. A simple RC filter or a more complex active filter can be used, depending on the specific application requirements.
  • The recommended clock frequency for the PCM1803ADB is between 256 fs and 512 fs, where fs is the sampling frequency. This ensures proper device operation and minimizes jitter.
  • The PCM1803ADB outputs 24-bit data in a MSB-first, left-justified format. The digital output data should be captured and processed by a microcontroller or DSP, taking care to handle the data format and word length correctly.
  • The PCM1803ADB has a thermal pad on the bottom of the package. A thermal management strategy should include a heat sink or thermal interface material to dissipate heat, ensuring the device operates within its recommended temperature range.
