The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
To optimize performance in noisy environments, use a low-pass filter on the input signal, ensure good power supply decoupling, and consider using a shielded enclosure to reduce electromagnetic interference.
The maximum clock frequency is 50 MHz, but it's recommended to use a clock frequency of 40 MHz or less to ensure reliable operation.
The DSD1796DBR outputs data in a 2's complement format. To handle this, use a microcontroller or FPGA to convert the data to a more suitable format, such as unsigned binary or floating-point.
Use a 4-layer PCB with a solid ground plane, and route the analog and digital signals separately to minimize noise coupling. Keep the analog input traces short and away from digital signals.
