PCM1704U-K/2K 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 PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the analog signal sources. Also, use short, direct traces for the analog signals and avoid crossing digital signals over analog signals.
  • The recommended clock frequency is between 256 fs and 512 fs, where fs is the sampling frequency. This range ensures proper device operation and minimizes jitter.
  • The digital output data is in two's complement format, MSB first. The data is output on the D0-D15 pins, with D15 being the MSB. The data is valid on the rising edge of the clock signal.
  • The VREF pin is the reference voltage input for the analog-to-digital converter. It sets the full-scale range of the converter and should be connected to a stable voltage source, typically between 4.5V and 5.5V.
