AD7891ASZ-1 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC before applying VREF. This ensures that the internal reference voltage is stable before the ADC starts converting.
  • To minimize noise and ensure accurate conversions, keep the analog and digital grounds separate, use a star-ground configuration, and keep the analog input traces away from digital traces. Also, use a low-ESR capacitor for the VREF pin.
  • The maximum sampling rate of the AD7891ASZ-1 is 250 kSPS. However, this rate can be affected by the clock frequency, conversion mode, and other factors. Refer to the datasheet for more information.
  • Use external voltage-limiting resistors or clamping diodes to protect the analog input pins from overvoltage conditions. The AD7891ASZ-1 has internal diodes that can handle up to 30 V, but external protection is still recommended.
  • Yes, the AD7891ASZ-1 can be used in a multiplexed configuration. However, you need to ensure that the multiplexer is properly synchronized with the ADC's conversion cycle to avoid errors.
