AD7890ANZ-2 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents damage to the device.
  • Check that the CONVST pin is being driven correctly, and ensure that the CS pin is low during the conversion process. Also, verify that the VREF pin is within the recommended range and that the analog input signal is within the specified range.
  • The maximum capacitance that can be connected to the REFOUT pin is 10nF. Exceeding this value may affect the stability of the internal reference voltage.
  • Yes, the AD7890ANZ-2 can be used in a multiplexed system. However, it's essential to ensure that the analog input signal is settled before starting a conversion, and that the multiplexer is properly synchronized with the converter.
  • The optimal value for the external capacitor connected to the CREF pin depends on the specific application and the desired noise performance. A good starting point is to use a 10nF capacitor, and then adjust the value based on the system's noise requirements.
