DSD1796DBR datasheet by Texas Instruments

DSD1796DBR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DSD1796DBR?
  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.
• How do I optimize the performance of the DSD1796DBR in noisy environments?
  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.
• What is the maximum clock frequency that can be used with the DSD1796DBR?
  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.
• How do I handle the output data format of the DSD1796DBR?
  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.
• What is the recommended layout and routing for the DSD1796DBR?
  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.
