UDA1330ATS/N2,118 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the UDA1330?
  The recommended power-up sequence is to apply VDD first, followed by VDDA, and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the UDA1330's performance for low-power applications?
  To optimize the UDA1330's performance for low-power applications, use the lowest possible clock frequency, disable unused features, and adjust the bias current to the minimum required for the application.
• What is the maximum allowed capacitance on the analog input pins?
  The maximum allowed capacitance on the analog input pins is 10nF. Exceeding this value may affect the device's performance and stability.
• Can I use the UDA1330 with a separate analog and digital power supply?
  Yes, the UDA1330 can be used with separate analog and digital power supplies. However, ensure that the analog power supply (VDDA) is decoupled from the digital power supply (VDD) using a ferrite bead or an inductor to minimize noise coupling.
• How do I troubleshoot issues with the UDA1330's analog-to-digital conversion?
  To troubleshoot issues with the UDA1330's analog-to-digital conversion, check the input signal amplitude, frequency, and impedance. Ensure that the input signal is within the specified range and that the analog input pins are properly terminated.
