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 for the PCM1704U-J/2K is between 256 fs and 512 fs, where fs is the sampling frequency. This frequency range ensures proper device operation and minimizes jitter.
The PCM1704U-J/2K outputs 24-bit data in a 2's complement format. The data should be latched on the rising edge of the clock signal, and the MSB (most significant bit) should be aligned with the clock signal.
The recommended operating temperature range for the PCM1704U-J/2K is -40°C to 85°C. Operating the device outside this range may affect its performance and reliability.
