ADS5422Y/250 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. Additionally, use short and direct traces for the analog inputs and outputs, and avoid crossing digital signals over the analog signals.
  • Use a 100-ohm differential termination resistor (RT) between the positive and negative analog input pins, and a 50-ohm series resistor (RS) on each input line to match the impedance of the source.
  • The recommended clock frequency is between 10 MHz to 40 MHz, and the clock signal should have a duty cycle of 40% to 60% and a rise/fall time of less than 1 ns.
  • The ADS5422Y/250 outputs 14-bit or 16-bit parallel data, depending on the mode. The output data is in two's complement format, and the data is valid on the rising edge of the clock signal.
  • The POR timing is approximately 10 ms, and the sequence is: VDD, then CLK, then AVDD. The device is ready for operation after the POR sequence is complete.
