PCM2902CDBR 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.
  • The analog input filter should be designed to reject noise and aliasing. A 3rd-order Butterworth filter with a cutoff frequency of 10 kHz to 20 kHz is recommended. The filter should also be designed to match the impedance of the analog input.
  • The recommended clock frequency is 256 fs, where fs is the sampling frequency. This ensures proper device operation and minimizes jitter.
  • The digital output data is in 2's complement format. The MSB (most significant bit) is the sign bit, and the remaining bits represent the magnitude. The data should be processed accordingly to ensure correct interpretation.
  • The PCM2902CDBR has a thermal pad that should be connected to a thermal plane or a heat sink to dissipate heat. A thermal interface material (TIM) can be used to improve heat transfer. The device should be operated within the recommended temperature range to ensure reliability.
